我应该用Java创建一个基于Swing和gui的服务器和客户端.我需要以某种方式建立一个从服务器到客户端,从客户端到服务器的套接字,并传递某种字符串.I我希望稍后有一个函数可以根据套接字中的字符串做几件事.
出于某种原因,我找不到一个简单的代码示例,它以简单的方式显示了它是如何完成的.
任何人都有任何简单的例子,或者可以解释它是如何完成的？

我的java版本是:

Java Plug-in 10.3.1.255使用JRE版本1.7.0_03-b05 Java HotSpot(TM)客户端VM

所以当我有版本6.x一切都很好,升级后我得到了这个:

关于我的问题(可能),我发现了另一种异常类型,我无法从SwingWorker线程中捕获和打印出来.

如何生成RepaintManager异常？

我读这CheckThreadViolationRepaintManager和该方法通过Alexander Potochkin,但似乎没有解决我的问题.
