如何添加按钮监听事件？请指教！！

[Cx_轩]

Button button = new Button("关闭"); button.addActionListener(new ActionListner(){(匿名内部类，创建一个事件监听类实现其中的actionPerformed方法) public void actionPerformed(ActionEvent e) { System.exit(0); //退出 } }) 希望可以帮到你！

之前写过的一个简单计算机，你看着完善自己的功能。都差不多。

[quote=引用 2 楼 沉默的拜金女的回复:]给我必须写全！

楼主这个语气好霸气啊[/quote] 按照一楼的格式，直接在Button实例化后的一句，加上一楼贴出的代码，将里面的退出语句改成相应的事件响应程序代码。
