案例展示：如何在Java中使用多线程

在Java中，我们可以利用Thread类来创建和管理多线程。以下是一个简单的案例，演示如何创建和执行两个线程：

public class MultiThreadExample {
    // 线程1的任务
    private Runnable task1 = () -> {
        System.out.println("Thread 1 is running任务.");
        try {
            Thread.sleep(2000); // 模拟耗时操作
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Thread 1 has completed its task.");
    };
    // 线程2的任务
    private Runnable task2 = () -> {
        System.out.println("Thread 2 is running task.");
        try {
            Thread.sleep(3000); // 模拟耗时操作
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Thread 2 has completed its task.");
    };
    public static void main(String[] args) {
        // 创建线程对象
        Thread thread1 = new Thread(task1);
        Thread thread2 = new Thread(task2);
        // 启动线程
        thread1.start();
        thread2.start();
        // 线程执行完成后，关闭程序
        try {
            thread1.join(); // 等待thread1结束
            thread2.join(); // 等待thread2结束
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
