Question

我想问一下，当第一次移动鼠标时，如何在定时器启动时进行60秒倒计时（并在标题中显示）。然后在最后我想显示一些jOptionPane.Message或其他东西。这是代码......

private void jPanel2MouseMoved(java.awt.event.MouseEvent evt)   {                                   
    jPanel1.setBounds(evt.getX(), evt.getY(), jPanel1.getWidth(), jPanel1.getHeight());
    int a = KEK.nextInt(jPanel2.getWidth()-15);
    int b = KEK.nextInt(jPanel2.getHeight()-15);
    if(jPanel1.getBounds().intersects(jPanel3.getBounds()) == true){
        rurin++;
        jPanel3.setBounds(a, b, jPanel3.getWidth(), jPanel3.getHeight());
        this.setTitle("Number of red dots touched: " +rurin+" ");
    } 
}

创建实现ActionListener的类的实例：示例EmilsListener list = new EmilsListener();
创建Timer类的实例，并传递对象及其重新启动的时间：Timer tym = new Timer(1000,list);
将侦听器添加到计时器，然后启动计时器：例如

tym.addActionListener(list);
tym.start();//But before this make sure you defined the EmilsListener class which must also contain your `jPanel2MouseMoved()` method.
