Java Swing -如何暂停方法并等待按键？

boolean isPaused = false;

Thread thread = new Thread(() -> {
    while (true) {
        if (!isPaused) {
            // 执行需要暂停的方法
        }
        try {
            Thread.sleep(100); // 控制方法执行的频率
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
});

thread.start();

frame.addKeyListener(new KeyAdapter() {
    @Override
    public void keyPressed(KeyEvent e) {
        if (e.getKeyCode() == KeyEvent.VK_SPACE) {
            isPaused = !isPaused; // 切换暂停状态
        }
    }
});

frame.setFocusable(true);
frame.requestFocus();
