服务器

package com.zhangry.interview.java.socket;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.ServerSocket;import java.net.Socket;public class Server {    private ServerSocket ss;    private Socket socket;    private BufferedReader in;    private PrintWriter out;    public Server(){         try {            ss = new ServerSocket(8888);            while(true){                socket = ss.accept();                String remoteIP =  socket.getInetAddress().getHostAddress();                String remotePort = ":"+socket.getLocalPort();                System.out.println("客户端接入 ! IP :"+remoteIP+remotePort);                in = new BufferedReader(new InputStreamReader(socket.getInputStream()));                String line = in .readLine();                System.out.println("客户端说 :"+ line);                out= new PrintWriter(socket.getOutputStream(),true);                out.println("你的信息已收到!");                out.close();                in.close();                socket.close();            }        } catch (IOException e) {            e.printStackTrace();        }    }        public static void main(String[] args){        new Server();    }}

客户端

package com.zhangry.interview.java.socket;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.Socket;import java.net.UnknownHostException;public class Client {    Socket socket;    BufferedReader in;    PrintWriter out;    public Client(){        try {            System.out.println("Try to connect to 127.0.0.1:8888");            socket = new Socket("127.0.0.1",8888);            System.out.println("已经成功连接至服务器");            System.out.println("请输入要发向服务器的话:");            BufferedReader line = new BufferedReader(new InputStreamReader(System.in));            out = new PrintWriter(socket.getOutputStream(),true);            out.println(line.readLine());            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));            System.out.println(in.readLine());            out.close();            in.close();            socket.close();        } catch (UnknownHostException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }    }        public static void main(String[] args){        new Client();    }}
