java实现客户端服务端互发消息并接收

基于TCP协议的服务器端
        1.创建服务器套接字，绑定端口号（new ServerSocket(1008)）
        2.侦听客户连接，返回socker(listener.accept())
        3.获输入、输出流
        4.处理数据
        5.关闭资源
		
		
基于TCP协议的客户端
            1.创建客户端套接字，指定服务器的地址和端口号
            2.获输入、输出流
            3.处理数据
            4.关闭资源

服务器已经启动
客户端说：你好啊，服务器

Process finished with exit code 0

服务端跟你说：你好啊，客户端

Process finished with exit code 0
