Answer 1

this是type JFrame 和ActionEvent不能对应

Answer 2

楼上正解.
解决方法:
把其中的this换成JoptionPaneFrame.this, 其他几个地方也作相同的更换.
jbutton4.addActionListener(new ActionListener()
{public void actionPerformed(ActionEvent ae){jbutton4_actionPerformed(this);}
}); 
------------------------------------------------------------------------------
jbutton4.addActionListener(new ActionListener()
{public void actionPerformed(ActionEvent ae){jbutton4_actionPerformed(JoptionPaneFrame.this);}
});

Answer 5

既然都给出了解决方案了.我就说两句无关的话.
一看你的代码就知道是jbuilder写的.其实你可以试下使用eclipse 的swt designer插件.它的事件添加方式更适合我们.个人觉得.jb自动完成的事件处理方式太伤心了
