Java Scoket实现双向通信代码详解

//构造器
public ServerSocket(int port)

//创建网络服务
ServerSocket server = new ServerSocket(9999);

//接收网络请求的方法
public Socket accept()

//网络服务接收请求（阻塞）
Socket socket = server.accept();

发送网络请求
//构造器
public Socket(String ip, int port)
//获取网络连接中的输入流
public InputStream getInputStream()
//获取网络连接中的输出流
public OuputStream getOutputStream()
