返回可中断线程的函数

public class InterruptibleThread extends Thread {
    @Override
    public void run() {
        while (!Thread.currentThread().isInterrupted()) {
            // 执行任务
            System.out.println("线程正在运行...");
            try {
                Thread.sleep(1000); // 模拟耗时操作
            } catch (InterruptedException e) {
                // 捕获中断异常，重新设置中断状态
                Thread.currentThread().interrupt();
                System.out.println("线程被中断");
                break; // 退出循环
            }
        }
    }

    public static void main(String[] args) throws InterruptedException {
        InterruptibleThread thread = new InterruptibleThread();
        thread.start();
        Thread.sleep(3000); // 主线程等待3秒
        thread.interrupt(); // 中断子线程
    }
