该楼层疑似违规已被系统折叠 隐藏此楼查看此楼

我自己做出了外部外形模块，找了很多资料，大致的思路是：

1，先创建外部界面，外圈用BorderLayout，内部用GridLayout，做出计算器面板。

2，为每个button注册监听器并且实现点击按钮上面的JTextArea板块会输出相应的按钮内容。

3，把每种情况都用if，else提前编写好，使用时可以满足所有计算。

但现在卡在了第二监听器注册完之后没办法实现点击之后JTextArea会输出对应文字，还有第三部没有任何思路，不知从何处下手。。。

下面是我的代码，求各位大神帮忙修改完成。。。我的第一个java项目，实在是没办法了。。
