Class and interface analysis and examples commonly used in "Concurrent" framework

"Concurrent" framework is an important tool in the Java programming language for implementing concurrent programming.It provides a set of classes and interfaces to handle the execution, synchronization and coordination of concurrent tasks.In this article, we will analyze the "Concurrent" framework class and interfaces commonly used, and provide the corresponding Java code examples. 1. Thread class: Thread class is the basic class of processing threads in Java.It provides ways to create and manage threads, such as start () and join ().The following is an example of creating and starting a new thread: public class MyThread extends Thread { public void run() { // The code to be executed thread } public static void main(String[] args) { MyThread thread = new MyThread(); thread.start(); } } 2. Runnable interface: The Runnable interface is a functional interface that defines a task that can be performed by the thread.It only contains one run () method.The following is an example of creating and starting a new thread using the Runnable interface: public class MyRunnable implements Runnable { public void run() { // The code to be executed thread } public static void main(String[] args) { MyRunnable runnable = new MyRunnable(); Thread thread = new Thread(runnable); thread.start(); } } 3. Executor interface: Executor interface is an object of executing task.It allows the submission of tasks to separate from the execution of the task.The following is an example of performing tasks using the Executor interface: Executor executor = Executors.newFixedThreadPool(5); executor.execute(() -> { // The task of execution }); 4. FUTURE interface: Future interface is an object that can be used to obtain asynchronous execution results.It provides a series of methods, such as get () and Cancel ().The following is an example of using the Future interface to obtain asynchronous execution results: ExecutorService executorService = Executors.newSingleThreadExecutor(); Future<Integer> future = executorService.submit(() -> { // The task of execution return 42; }); // Get the execution result of the task try { Integer result = future.get(); System.out.println ("Result:" + Result); } catch (InterruptedException | ExecutionException e) { e.printStackTrace(); } 5. LOCK interface: Lock interface provides a more flexible lock mechanism than Synchronized keywords.It defines a series of methods such as lock () and unlock ().The following is an example of using the Lock interface to synchronize thread: Lock lock = new ReentrantLock(); try { lock.lock(); // Critical area code } finally { lock.unlock(); } The above is the analysis and examples of class and interfaces commonly used in the "Concurrent" framework.By using these classes and interfaces flexibly, you can achieve efficient concurrent programming.
