java socket 客户端和服务器端互相通信（聊天）

客户端：

package com.lzx.socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class SocketClient {

  public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub
    final Socket socket = new Socket("127.0.0.1", 10000);
      
    //回复服务端
    new Thread(){
      public void run() {
        try {
          PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
          BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
          String readline = in.readLine();
          System.out.println(readline);
          while(true){
            out.println(readline);
            System.out.println(" client send: " + readline);
            readline = in.readLine();
            if(readline.equals("bye"))
              break;
          }
        } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
        }
      };
    }.start();
    
    
    new Thread(){
      public void run() {
        //获得客户端发来的数据
        try {
          BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
          while(true){
            System.out.println("Receive from server : " + reader.readLine());
          }
        } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
        }
      };
    }.start();
    
    
  }

}

服务端：

package com.lzx.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 SocketServer {

  public static void main(String[] args) throws IOException {
    ServerSocket server = new ServerSocket(10000);
    final Socket socket = server.accept();
    
    new Thread(){
      public void run() {
        //获得客户端发来的数据
        try {
          BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
          while(true){
            System.out.println("Receive from client : " + reader.readLine());
          }
        } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
        }
      };
    }.start();
    
    new Thread(){
      public void run() {
        try {
          PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
          BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
          String readline = in.readLine();
          System.out.println(readline);
          while(true){
            out.println(readline);
            System.out.println(" server send: " + readline);
            readline = in.readLine();
            if(readline.equals("bye"))
              break;
          }
        } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
        }
      };
    }.start();
