Java Swing -how让一个线程一直处于休眠状态，并通过单击唤醒它？

public class MyThread extends Thread {
    private boolean isPaused = true;

    public void setPaused(boolean paused) {
        isPaused = paused;
    }

    @Override
    public void run() {
        while (true) {
            try {
                synchronized (this) {
                    while (isPaused) {
                        wait();
                    }
                }
                // 执行需要休眠的操作
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

JButton button = new JButton("唤醒线程");
button.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        myThread.setPaused(false);
        synchronized (myThread) {
            myThread.notify();
        }
    }
});

MyThread myThread = new MyThread();
myThread.start();
