java - 如何在处理时添加 Action 监听器

Question

我想在窗口关闭时停止声音，如何在处置时添加 Action 监听器？

 public Tetris(boolean sound) {

    statusbarLabel = new JLabel(" 0");
    add(statusbarLabel, BorderLayout.SOUTH);
    Board board = new Board(this);
    if(sound){
        Sound.gameSound.play();
    }

    add(board);
    board.start();


    setSize(200, 400);
    setTitle("Tetris");
    setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    this.setLocationRelativeTo(null);
    this.setVisible(true);

}

最简单的方法是添加一个WindowListener:

addWindowListener(new WindowAdapter() {

   @Override
   public void windowClosing(WindowEvent e) {
     Sound.gameSound.stop();
   }
});
