Java 21 Examples

Virtual Threads Virtual threads enable high-throughput concurrent applications with lightweight threads. <code> // Creating and starting a virtual thread Thread virtualThread = Thread.ofVirtual().start(() -> { System.out.println("Hello from virtual thread!"); }); virtualThread.join(); // Creating virtual threads with custom names Thread.Builder builder = Thread.ofVirtual().name("MyVirtualThread"); Runnable task = () -> System.out.println("Running in: " + Thread.currentThread().getName()); Thread thread = builder.start(task); thread.join(); // Using ExecutorService with virtual threads try (ExecutorService executor = Executors.newVirtualThreadPerTaskExecutor()) { for (int i = 0; i < 1000; i++) { int taskId = i; executor.submit(() -> { System.out.println("Task " + taskId + " running on virtual thread"); }); } } // Executor automatically closes and waits for tasks </c...

Exploring Java 21: New Features, Enhancements

Introduction: Java, the widely-used programming language, has been continuously evolving over the years to meet the ever-changing demands of the software industry. With the release of Java 21, developers can expect a plethora of new features, enhancements, and exciting changes. In this blog post, we will delve into the key highlights of Java 21, provide code samples, discuss proposed changes, and explore the release date. Let's dive in! 1. Records: Java 21 introduces the "records" feature, which aims to simplify the creation of immutable data objects. With records, you can declare a class with concise syntax, and the compiler automatically generates the constructor, accessors, `equals()`, `hashCode()`, and `toString()` methods. Here's an example: public record Person(String name, int age) {} Person john = new Person("John", 25); System.out.println(john); // Output: Person[name=John, age=25] 2. Pattern Matching for Switch: Java 21 enhances the switch state...
