我真的不会啊！请问各位高手这样的一个计算器怎样做啊？麻烦给出源代码？小女子感激不尽！

请问贴名是？

兄弟a＊１０　是什么意思啊．

用个循环可以让代码更精练

to 曾啊牛

首先，我必须敬佩你的毅力~~你让我想起以前的我，也是那么的热情，那么的有精力

但是，我必须还是得说：这样写这个软件!
you make a mistake!

我们先说实现的细节错误
1.对于一个计算器，我们一接手马上就应该意识到，要检查除数不能为0！！！这也是我测试的第一个计算！ 很遗憾，你没通过...
2.输出的“液晶”显示屏你是用个JTextarea代替的，这很对，但是你也要设置一下不能编辑吧，如果我往里面输入的字母，你知道会发生什么情况吗？

再说说实现的设计错误
1.难道你打了那么多的JButton就没意识到，其实这是可以作为一个类的么！这样连楼9的意思都不用~
2.写swing的时候，极力不推荐采用坐标方式安插对象，比如JButton2.setBounds(60, 60, 60, 60);因为只要用户一旦改变了分辨率，你这个坐标就全乱了，当然这个对这个计算器那么小的项目来说根本就没有用Layout Managers的必要，但是为了你的以后的大设计中不出现这样的代码，我还是忍不住和你说说。

最后我还要说说整个程序的设计错误~
界面设计应该要与逻辑设计相分离，对于这个错误嘛~~你同样也可以不理会，这个要求是有点苛刻了的，起码对于这个小小的计算器来说，但是我记得我也是从计算器学起的。

我说那么多，其实不是针对这个计算器的，这个计算器除了我前面说的那些实现的错误以外，其他还算是勉强的，特别是这个程序的ActionListener的实现让我又学会了一个实现的方法~谢谢
我看了你最近的帖子，知道你要做一个药店管理的软件~~根据你现在的知识，我想你应该是打算往C/S方向发展的。祝你顺利~

我早在几个月前（呵呵，现在的电脑知识都是按月计的）就放弃了java的桌面应用程序设计~因为java在桌面应用上是不可能和已经完全绑定、整合到windows操作系统的vc++、c#相比的。Linux/unix下java就更加慢了~要知道玩Linux/Unix的人不是网管就是C语言N牛的程序设计员...
