Socket通信

Server

1.创建服务器指定端口 ServerSocket server =new ServerSocket(); 2.接收客户端连接 阻塞式 Socket socket =server.accept(); System.out.PRintln("客户端建立成功"); 3.发送数据 String meg="欢迎使用"; //输出流 BufferedWriter bw = new BufferedWriter( new OutputStreamWriter(socket.getOutputStream()));

Client

1.创建客户端 必须指定服务器+端口 Socket client = new Socket("localhost",8888); 2.接收数据 BufferedReader br = new BufferedReader(new InputStreamReader(client.getInputSteram())); String echo = br.readLine(); System.out.println(echo);
