解决方案五：
根本看不完
解决方案六：
自己尝试调试解决吧
解决方案七：
代码太长。楼主先学会怎么去问问题
解决方案八：
如果是根据视频学的话，那你写的代码你肯定知道是哪部分的，你说另外一端的client不消失，那你把client消失的代码拷出来就行了，把全部代码拉下来没人看的。
解决方案九：
我只能说，兄弟，主意形象，要考虑到看帖人的感受
解决方案十：
我擦从来没见过这么牛逼的帖子
解决方案十一：
AWT/Swing是很老的javaGUI编程接口，建议楼主不要再在这上面花精力了，现在主流都是J2EE，即使是桌面应用也是SWT/Jface的天下
解决方案十二：
如果这些代码是楼主又敲的，而不是复制的话，我猜楼主应该已经自己找到问题了吧
解决方案十三：
楼主，膜拜你。
解决方案十四：
直接吓尿了
解决方案十五：
不考虑别人的感受，连代码引用都没加。
解决方案：
不写点注释？
