1.现在刚学Java网络编程,编写的客户端和服务器端程序只能运行一次,第二次运行就会出现异常,异常如下: Exception in thread "main" java.net.BindException: Address already in use: JVM_Bind at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(Unknown Source) at java.net.ServerSocket.bind(Unknown Source) at java.net.ServerSocket.<init>(Unknown Source) at java.net.ServerSocket.<init>(Unknown Source) at Server.Server.main(Server.java:359) 好像是地址或者端口号里面有问题吧?
