昨晚上发的帖子现在0回复，谈什么复兴

我觉得吧里应该定期搞一些活动，比如编程大赛呀。会员见面呀。贴吧之星之类的，这样能提高大家的热情的积级性。

牛逼点的资源分享  牛逼点的技术文章  再来点活动

广告铺天盖地，吧主无能，去海吧学习去

建立个交流平台，分享资源~定期做些活动等等……

ok，大家的建议挺好的，我会尽快着手办。

把会员要求降低吧 20条帖子那个

泡吧喝酒

帮我写个程序嘛！ 编写程序完成简单计算器的功能：加、减、
Number1、Number2、Result 是三个JLabel 控件，它们后面的是三个 JTextField控件，用来输入操作数并显示运算结果；窗体下边是四个JButton控件Add、Subtract、Multiply、Divide,分别代表加、减、乘、除运算，点击是进行相应的运算并显示结果；窗体上边的菜单完成同样的功能。<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 乘、除
