11 New Features Introduced in JDK 11

 follows a six-month release cycle, and on September 25, 2018, Oracle officially released JDK 11. This version is particularly important as it’s the first Long-Term Support (LTS) release following the new release model. As a result,  11 has become a key version for enterprise environments.

It is worth noting that Oracle JDK 11 is no longer free for commercial use, meaning businesses must obtain a license. For those not willing to purchase Oracle’s commercial support, OpenJDK alternatives are available from vendors like Red Hat, Amazon Corretto, and Azul Systems.

Let’s examine the major features  11 brings to the table:

Java 11 Updates: Enhanced Code Efficiency with Lambda Improvements and String Methods

Java 11, the long-term support (LTS) version of the Java programming language, brought several key enhancements and updates that simplify common tasks, increase efficiency, and allow developers to write cleaner and more maintainable code. Among these improvements, two areas stand out—lambda parameter type inference and the addition of several useful methods to the String class. These updates enable more concise, expressive, and flexible code.

In this article, we will explore how these two updates—lambda parameter type inference and the new String methods—can enhance your Java programming experience and boost your development productivity. These changes not only improve the clarity of code but also provide developers with powerful tools to simplify complex tasks. Let’s dive into the specifics of how these features work.

Lambda Parameter Type Inference with var

Java 11 introduces a significant improvement to lambda expressions through lambda parameter type inference using the var keyword. Prior to this release, Java developers had to explicitly specify the type of the parameters used in lambda expressions. This often resulted in verbose code, especially when working with generic types. With Java 11, the introduction of var for lambda parameters eliminates the need for these explicit type declarations, making the code more concise and readable.

What is Lambda Parameter Type Inference?

Lambda parameter type inference allows you to use the var keyword in lambda expressions to let the compiler automatically infer the type of the parameters. This change provides the same level of type safety but without the need to declare the types explicitly. The primary advantage of this feature is that it reduces boilerplate code and improves consistency when dealing with lambda expressions, making it easier to read and write code.

Example of Lambda Parameter Type Inference in Java 11

Let’s take a look at a typical lambda expression before and after the var update.

Before Java 11 (explicit parameter types):

Function<String, String> append = (String s) -> s + “!”;

In the above code, we have to explicitly specify the type of the parameter s as String. This can make the code unnecessarily verbose, especially when the type is obvious from the context.

After Java 11 (using var for parameter type inference):

Function<String, String> append = (var s) -> s + “!”;

With the introduction of var in lambda parameters, the type of s is inferred by the compiler based on the target type of the lambda expression, which in this case is String. As a result, the type declaration for the parameter is no longer necessary, which simplifies the code.

Benefits of Lambda Parameter Type Inference

  1. Cleaner Code: By eliminating the need for explicit type declarations, your code becomes cleaner and more concise. Developers can focus on the logic of the lambda expression rather than being bogged down with repetitive type information.
  2. Consistency: The var keyword for lambda parameters aligns with how var is used in local variables in Java. This creates consistency across the language, making the code easier to understand and maintain.
  3. Increased Readability: The simplified syntax helps improve the readability of lambda expressions, which are often used in functional programming tasks such as filtering, mapping, or reducing data. This is especially beneficial in complex functional chains where you don’t want to be distracted by redundant type declarations.
  4. Improved Development Speed: For Java developers, writing code without needing to specify types for lambda parameters can significantly speed up development. This becomes particularly useful in large codebases or when working with libraries that make heavy use of functional interfaces.

New String Methods: Making String Manipulation Easier

Java 11 also introduced several new and improved methods for manipulating strings. These methods aim to make common string operations more efficient, intuitive, and less error-prone. Let’s take a closer look at the new String methods that are now part of the Java standard library.

1. isBlank(): Check if a String is Empty or Contains Only Whitespace

The isBlank() method checks whether a string is empty or contains only whitespace characters. This is an extremely useful method for string validation, as it eliminates the need to manually check for empty strings or strings that only contain spaces.

Example:

String str1 = ”   “;

String str2 = “Hello World”;

System.out.println(str1.isBlank()); // Output: true

System.out.println(str2.isBlank()); // Output: false

In the above example, str1 is a string consisting only of spaces, so isBlank() returns true. On the other hand, str2 is a non-blank string, so the method returns false.

2. lines(): Convert a Multiline String into a Stream of Lines

The lines() method converts a multiline string into a stream of lines. This method is particularly useful when dealing with large chunks of text or files, as it allows you to process each line individually using stream operations. Instead of manually splitting a string into lines, you can now simply call lines() and apply stream methods such as map(), filter(), or forEach().

Example:

String multiline = “Hello\nWorld\nJava”;

multiline.lines().forEach(System.out::println);

This code takes a multiline string and prints each line separately. The output will be:

Hello

World

Java

3. strip(), stripLeading(), and stripTrailing(): Improved Whitespace Removal

Before Java 11, developers used trim() to remove whitespace from both ends of a string. However, the trim() method was not always reliable, as it removed only the ASCII whitespace characters. In contrast, the new strip() method handles Unicode whitespace characters as well, making it a more robust solution for removing leading and trailing spaces.

  • strip(): Removes leading and trailing whitespace.
  • stripLeading(): Removes only leading whitespace.
  • stripTrailing(): Removes only trailing whitespace.

Example:

String str = ”  Java  “;

System.out.println(str.strip());        // Output: “Java”

System.out.println(str.stripLeading()); // Output: “Java  “

System.out.println(str.stripTrailing()); // Output: ”  Java”

These methods are more efficient and flexible compared to trim() and are useful when working with strings that may contain non-ASCII whitespace characters, such as those from different languages.

4. repeat(int): Repeat a String Multiple Times

The repeat(int) method allows you to repeat a string a specified number of times. This is a straightforward but very helpful method for tasks that require repeated patterns or for formatting output.

Example:

String str = “Java “;

System.out.println(str.repeat(3)); // Output: “Java Java Java “

In this example, the string “Java ” is repeated three times, producing the result “Java Java Java “.

How These Updates Improve Developer Productivity

The introduction of lambda parameter type inference and new String methods in Java 11 significantly improves developer productivity and code quality. These features are designed to reduce the boilerplate code that often makes Java applications verbose and difficult to maintain. The lambda improvements simplify functional programming syntax, while the String enhancements streamline common string operations that would otherwise require more verbose or manual approaches.

By embracing these updates, Java developers can now write cleaner, more efficient, and more readable code. Additionally, these new methods enhance performance and maintainability, which are critical in building high-quality, scalable applications.

Embrace Java 11 for Simplicity and Efficiency

Java 11 brings powerful enhancements that simplify common tasks in the language, such as lambda parameter type inference and improvements to the String class. With the ability to use var in lambda expressions, developers can write more concise code that is easier to maintain. The addition of methods like isBlank(), lines(), strip(), and repeat() in the String class eliminates the need for manual and error-prone operations, making string manipulation simpler and more reliable.

As you continue to build and maintain Java applications, leveraging these new features will not only make your codebase cleaner but will also improve your productivity and the overall quality of your code. By upgrading to Java 11 and adopting these features, developers can stay ahead of the curve and write more efficient, modern Java applications.

In this detailed overview, we will explore some of the most impactful changes in Java 11, including Unicode 10 support, the new HTTP Client API, enhancements to collection handling, and the introduction of the Epsilon Garbage Collector.

Unicode 10 Support: Enabling Globalization and Better Internationalization

One of the standout updates in Java 11 is the inclusion of Unicode 10 support, which brings over 16,000 new characters to the Java platform. This is a significant update for developers working on international applications, as Unicode 10 includes new symbols, emojis, and scripts that were previously unavailable in earlier Java versions. Some of the notable characters introduced include the Bitcoin symbol, new emojis, and various lesser-known writing systems, such as Adlam, Marchen, and Tangut.

Why Unicode 10 Matters

Unicode 10 broadens the scope for developers to handle a more diverse range of characters across various languages, symbols, and modern digital communication needs. In an increasingly interconnected world, globalization and localization are key considerations for software development. This support for more diverse characters in Java 11 is particularly valuable for:

  1. Multi-Language Applications: With Unicode 10, Java 11 allows for the development of truly global applications that can support multiple languages, regional symbols, and cultural representations.
  2. Improved Emoji Support: Emojis are widely used in applications, social media platforms, and messaging systems, and Java 11 ensures that all modern emojis are rendered correctly, further enhancing user experience.
  3. Support for Historic and Rare Scripts: The inclusion of Adlam, Marchen, and Tangut scripts opens doors for developers working on projects in regional and cultural contexts that use these ancient writing systems.

Example of Unicode 10 Usage

Java developers can now seamlessly use these new Unicode characters in their strings and applications. For example:

String bitcoinSymbol = “\u20BF”; // Bitcoin Symbol

String emoji = “\uD83D\uDE00”;  // Grinning Face Emoji

String adlam = “𐩻𐩴𐩱”; // Adlam script

 

System.out.println(bitcoinSymbol); 

System.out.println(emoji); 

System.out.println(adlam);

With the support for Unicode 10 in Java 11, these characters are now fully supported, making it easier to handle diverse user input and improve the overall user experience.

HTTP Client API: Full Standardization for Seamless HTTP Requests

Java 11 takes the HTTP Client API, which was initially introduced as an incubator module in Java 9, and fully standardizes it. The HTTP Client API provides developers with a powerful, modern way to interact with HTTP services. With full support for both synchronous and asynchronous calls, as well as HTTP/2 and WebSockets, the Java 11 HTTP Client becomes an essential tool for building high-performance networked applications.

Key Features of the Java 11 HTTP Client API

  1. Synchronous and Asynchronous Support: The HTTP Client API in Java 11 allows for both blocking (synchronous) and non-blocking (asynchronous) operations, giving developers the flexibility to choose the right approach for their application’s requirements.
  2. Support for HTTP/2: Java 11’s HTTP Client fully supports HTTP/2, a major improvement over the HTTP/1.x protocol, offering faster communication, better compression, and improved multiplexing, which leads to better performance, especially for large-scale applications.
  3. WebSocket Support: In addition to HTTP/2, the HTTP Client also supports WebSockets, which are crucial for building real-time applications, such as live chat systems or real-time data feeds.
  4. Simplified Code: The new HTTP Client API provides a more intuitive and streamlined API for sending HTTP requests compared to older approaches using HttpURLConnection.

Example Usage of HTTP Client API in Java 11

Here’s a simple example of how to make a synchronous HTTP request in Java 11 using the new HTTP Client

HttpClient client = HttpClient.newHttpClient();

HttpRequest request = HttpRequest.newBuilder()

    .uri(URI.create(“https://example.com”))

    .build();

 

HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());

 

System.out.println(“Response: ” + response.body());

This example demonstrates how easy it is to make an HTTP request using the modern HTTP Client API. The ability to handle both synchronous and asynchronous calls in one API is a huge benefit for developers, as it provides flexibility depending on the application’s performance needs.

New Collection Method: toArray(IntFunction)

Java 11 introduces a new method in the Collection interface called toArray(IntFunction<T[]>). This method simplifies the conversion of collections into arrays, making the code cleaner and less error-prone.

Why the toArray(IntFunction) Method Is Important

Before Java 11, developers had to manually cast the output of toArray() into the correct array type, which could sometimes lead to ClassCastException errors. With the toArray(IntFunction) method, Java 11 allows developers to directly specify the array type, improving type safety and reducing the chances of runtime errors.

Example Usage of toArray(IntFunction)

In Java 11, the toArray(IntFunction) method can be used like this:

List<String> list = List.of(“Apple”, “Banana”, “Cherry”);

String[] array = list.toArray(String[]::new);

 

System.out.println(Arrays.toString(array));

In this example, String[]::new is passed as the argument to specify the type of the array. This eliminates the need for manual type casting and ensures that the array is correctly typed, reducing the chance of errors.

Epsilon: A No-Op Garbage Collector for Performance Testing

Java 11 introduces the Epsilon Garbage Collector (GC), a unique and experimental garbage collector that does not reclaim memory. The Epsilon GC is specifically designed for performance testing and memory pressure simulation.

Use Cases for Epsilon GC

The Epsilon GC does not perform traditional garbage collection activities, making it ideal for certain scenarios where developers want to simulate memory behavior or measure the impact of memory allocation without the interference of garbage collection.

  1. Performance Testing: Developers can use Epsilon GC to assess how their application behaves under different memory loads without the background noise of garbage collection activities.
  2. Memory Pressure Simulation: In scenarios where memory usage needs to be explicitly controlled or simulated, Epsilon GC provides a clear and controlled environment.

Enabling Epsilon GC

To enable the Epsilon GC in Java 11, use the following JVM flags:

-XX:+UnlockExperimentalVMOptions -XX:+UseEpsilonGC

This configuration tells the JVM to use the Epsilon GC instead of the default garbage collector. It’s important to note that this garbage collector is mainly intended for specialized use cases like benchmarking and stress testing.

The Power of Java

Java 11 is packed with new features that make it a more powerful and flexible platform for modern application development. With Unicode 10 support, the language becomes more capable of handling diverse character sets, including new scripts, emojis, and symbols.

These updates span several areas including heap profiling, security improvements, garbage collection, and file I/O capabilities. With Java 11, developers can optimize their applications, improve security practices, and enhance performance through innovative features like low-overhead heap profiling, the Z Garbage Collector (ZGC), and enhanced key management for keystores. These features, along with dynamic allocation of compiler threads and new utility methods for file operations, help Java 11 emerge as a powerful platform for both enterprise-level applications and cloud-native services.

Let’s dive deeper into these key enhancements and discuss their impact on development and performance.

Low-Overhead Heap Profiling: Optimizing Memory Usage with Minimal Performance Impact

Java 11 introduces a low-overhead heap profiling mechanism via the Java Virtual Machine Tool Interface (JVMTI). Heap profiling enables developers to monitor memory allocation and usage within an application, allowing for detailed insights into how objects are allocated, stored, and eventually garbage collected.

However, traditional heap profiling mechanisms often come with significant performance overhead, especially in production environments. The low-overhead heap profiling introduced in Java 11 addresses this issue, offering a way to sample object allocations with minimal impact on the application’s performance. This is a game-changer, particularly when applications are running in production environments where low-latency and high-throughput are critical.

Key Benefits of Low-Overhead Heap Profiling:

  1. Production-Ready Monitoring: Developers can now monitor their applications’ heap usage in real-time without worrying about the overhead typically associated with profiling tools. This allows for more accurate performance monitoring in production, which is especially valuable in large-scale systems.
  2. Memory Management Optimization: With the insights gained from heap profiling, developers can optimize their applications’ memory usage, identify memory leaks, and better understand the performance characteristics of different components within their applications.
  3. Minimal Performance Impact: Unlike traditional heap profiling methods, this new approach minimizes the impact on the application’s runtime, ensuring that monitoring does not introduce significant performance degradation.

Enhanced KeyStore Security: Strengthening Data Protection

Security is a paramount concern in any software development lifecycle, and Java 11 has introduced an important feature designed to enhance the security of cryptographic operations: JCEKS keystore security. With the introduction of the jceks.key.serialFilter security property, Java 11 improves the security of encrypted keys stored in Java Cryptography Extension KeyStore (JCEKS) files.

Keystores are commonly used to store sensitive data, such as private keys and certificates, which are used to establish secure connections. With Java 11, when deserializing encrypted keys from a JCEKS keystore, filters are applied to ensure that only specific, authorized types of objects are allowed to be loaded. This reduces the risk of potential security vulnerabilities that could arise from deserializing untrusted objects.

Why is Enhanced KeyStore Security Important?

  1. Better Protection Against Security Risks: By applying filters to the deserialization process, Java 11 adds an extra layer of security, preventing unauthorized or malicious code from being executed during key loading operations.
  2. Stronger Key Management: The ability to apply filters to the deserialization of encrypted keys strengthens key management practices, ensuring that sensitive information is properly secured.
  3. Compliance with Modern Security Standards: Many organizations need to adhere to strict security standards, and Java 11’s enhanced keystore security ensures compliance with these regulations by mitigating the risk of attacks like deserialization vulnerabilities.

Z Garbage Collector (ZGC): Paving the Way for Low-Latency Applications

The Z Garbage Collector (ZGC) is a revolutionary feature in Java 11, designed to handle large heap sizes while maintaining extremely low-latency garbage collection. ZGC is an experimental low-latency garbage collector that is capable of handling heaps ranging from 100MB to several terabytes, all while ensuring that GC pause times remain under 10ms.

Traditionally, garbage collection (GC) pauses have been a concern for applications that require real-time processing, such as high-frequency trading systems, video streaming services, or large-scale cloud applications. ZGC is designed to address these concerns, offering continuous application responsiveness with very brief pause times.

Why ZGC Matters

  1. Low-Latency Applications: ZGC is ideal for applications that demand high responsiveness, such as real-time data processing, where even brief garbage collection pauses could negatively affect the user experience.
  2. Handling Large Heaps: ZGC can handle very large heap sizes with ease, making it suitable for large-scale enterprise applications and big data processing systems that require significant amounts of memory.
  3. Minimal Pause Times: One of the major selling points of ZGC is its ability to keep pause times consistently under 10ms, even under heavy workloads. This ensures a smooth and uninterrupted application flow.
  4. Experimental but Valuable: Although ZGC is still considered an experimental garbage collector in Java 11, it holds a lot of potential for developers working on applications that require ultra-low latency and high performance.

Enabling ZGC in Java 11

To enable the ZGC in Java 11, developers can use the following JVM flags:

-XX:+UnlockExperimentalVMOptions -XX:+UseZGC

These flags instruct the JVM to use ZGC for garbage collection, making it an excellent choice for developers working on latency-sensitive applications.

Dynamic Allocation of Compiler Threads: Optimizing Resource Utilization

Java 11 introduces the ability to dynamically manage the number of compiler threads based on runtime conditions. This dynamic approach replaces the previous static model where a fixed number of compiler threads were created at startup, regardless of the actual workload or system resources available.

This enhancement aims to improve resource efficiency by allowing the JVM to allocate the right amount of compiler threads based on the system’s current state, which leads to better utilization of available CPU resources.

Why Dynamic Allocation of Compiler Threads Is Important

  1. Improved Resource Efficiency: With dynamic thread allocation, Java 11 ensures that the JVM doesn’t waste resources on unnecessary threads, leading to better system performance, especially in resource-constrained environments.
  2. Faster Compilation Times: By allocating compiler threads dynamically, the JVM can optimize the compilation process and ensure faster startup and overall performance.
  3. Adaptability to Varying Workloads: The dynamic allocation of compiler threads allows the JVM to adapt to changing workloads, ensuring that it can scale efficiently across different types of applications.

Enabling Dynamic Compiler Thread Allocation

To enable dynamic compiler thread allocation in Java 11, use the following JVM flag:

-XX:+UseDynamicNumberOfCompilerThreads

This flag allows the JVM to allocate compiler threads based on runtime conditions, which can lead to improved application performance.

New File I/O Methods: Simplifying File Operations

Java 11 introduces several new utility methods in the Files class that simplify common file operations. These methods improve both the ease of use and performance of file-related tasks, making it easier for developers to handle file I/O operations.

New Methods in the Files Class:

  1. readString(Path): Reads the content of a file and returns it as a String. This method simplifies reading files, eliminating the need for manually handling InputStream or BufferedReader.
  2. writeString(Path, String): Writes a String to a file, making it easier to perform file writing operations without dealing with streams.
  3. isSameFile(Path, Path): Checks if two paths refer to the same file. This method is useful for avoiding redundant file operations and improving file handling logic.

Example Usage of New File I/O Methods

Here is an example demonstrating the use of the new file I/O methods:

Path path = Files.writeString(Path.of(“test.txt”), “Java 11 features are amazing!”);

String content = Files.readString(path);

System.out.println(“File Content: ” + content);

This code snippet showcases the simplicity and power of the new file I/O methods, which make file handling in Java easier and more efficient.

A Modern and Efficient Platform for the Future

Java 11 is a transformative release for developers and organizations looking to build high-performance, secure, and scalable applications. As the first Long-Term Support (LTS) version after Java 8, it introduces a suite of powerful features that enhance performance, bolster security, and streamline development processes.

ZGC is designed for applications that require ultra-low pause times, even when working with large heaps that range from 100MB to several terabytes. The main advantage of ZGC is its ability to keep GC pause times under 10ms, which is a game-changer for applications that require constant and uninterrupted execution, such as high-frequency trading platforms, real-time data processing systems, and cloud-native services.

For developers, this means that Java 11 offers a robust solution for memory management that is optimized for high-performance environments where even brief interruptions can impact user experience or system stability. By minimizing the GC pause times, the ZGC ensures that applications remain responsive and capable of handling large amounts of data without latency issues.

3. Dynamic Allocation of Compiler Threads: Enhancing Resource Efficiency

Java 11 introduces the ability to dynamically allocate compiler threads based on runtime conditions, optimizing system resources. Previously, the JVM would create a static number of compiler threads at startup, regardless of the actual workload. This could lead to inefficiencies in resource utilization, especially on systems with limited CPU capacity. With Java 11, the JVM can now adjust the number of compiler threads dynamically depending on the available resources, which results in more efficient resource utilization and better overall application performance.

This dynamic allocation is particularly beneficial in cloud environments where resources can fluctuate based on demand. It ensures that the system adapts in real-time to workload changes, allowing developers to achieve optimal performance without overcommitting or underutilizing system resources.

4. Enhanced Keystore Security: Safeguarding Sensitive Data

As security continues to be a top priority for modern applications, Java 11 introduces enhanced protection for sensitive data through improved keystore security. The jceks.key.serialFilter property added in Java 11 enhances the security of Java Cryptography Extension KeyStores (JCEKS). When deserializing encrypted keys, filters are applied to ensure that only trusted types are allowed to be loaded, mitigating the risk of deserialization vulnerabilities.

This feature is essential for applications that store and manage sensitive information such as cryptographic keys and certificates. With these enhancements, Java 11 enables developers to follow best practices for key management and ensure that encrypted data remains secure throughout its lifecycle.

5. New File I/O Methods: Streamlining File Operations

Java 11 introduces new, convenient methods for handling file I/O operations, making it easier for developers to work with files. Two new methods in the Files class—readString and writeString—simplify the process of reading from and writing to files by directly dealing with strings, eliminating the need for verbose stream handling. This improvement streamlines the file operation workflow and improves code readability.

Additionally, the isSameFile method allows developers to easily compare two file paths to check if they point to the same file. This functionality can be particularly useful in scenarios where file manipulation or file system operations are required.

These enhancements to file handling are especially helpful for developers working with configuration files, logs, or any application that frequently interacts with file systems. They significantly reduce the complexity of file operations and improve the overall efficiency of the code.
