Java:如何中断/停止线程？

public class StoppableThread extends Thread {
    private volatile boolean stopRequested = false;

    public void requestStop() {
        stopRequested = true;
    }

    @Override
    public void run() {
        while (!stopRequested) {
            // 执行任务
        }
    }
}

public class StoppableThread extends Thread {
    @Override
    public void run() {
        try {
            while (!isInterrupted()) {
                // 执行任务
            }
        } catch (InterruptedException e) {
            // 处理异常
        }
    }
}

public class StoppableThread extends Thread {
    private boolean stopRequested = false;

    public synchronized void requestStop() {
        stopRequested = true;
    }

    @Override
    public void run() {
        while (!stopRequested) {
            synchronized (this) {
                // 执行任务
            }
        }
    }
}
