第一步：建立一个服务器类
public class Server {

public static void main(String[] args) {

  //启动服务器接收线程
  ServerReceiver1 sr = new ServerReceiver1();

  Thread t1 = new Thread(sr);

  t1.start();


  //启动服务器发送线程
  ServerSend2 ss = new ServerSend2();

  Thread t2 = new Thread(ss);

  t2.start();
}
}
第二步：建立一个客户端的类
public class Client {

public static void main(String[] args) {
  //启动客户端发送线程
  ClientSend1 cs = new ClientSend1();

  Thread t1 = new Thread(cs);

  t1.start();

  //启动客户端接收线程

  ClientReceiver2 cr = new ClientReceiver2();

  Thread t2 = new Thread(cr);

  t2.start();
}
}
第三步：

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Scanner;

public class ClientSend1 implements Runnable{

public void run(){
  send();
}

public void send() {
  //一.建立socket连接
  //2.客户端申请连接
  //只是申请连接还没真正接通相当于打电话拨号对方不一定接
  Socket s = null;
  try {
   s = new Socket("localhost",8888);
  } catch (UnknownHostException e) {
   System.out.println("找不到主机,连接失败");
   e.printStackTrace();
  } catch (IOException e) {
   System.out.println("建立socket连接失败");
   e.printStackTrace();
  }

  //二.I/O操作
  //1.建立通道
  OutputStream os = null;
  try {
   os = s.getOutputStream();
  } catch (IOException e) {

   e.printStackTrace();
  }

  PrintWriter pw = new PrintWriter(os);


  Scanner scanner = new Scanner(System.in);
  System.out.println("---------client---------");
  System.out.println("请输入您想说的话:");

  String str = scanner.next();
  //2.利用write写
  pw.println(str);
  pw.flush();

  //---------------------一直说-----------------------
  while(!str.equals("88")){
   System.out.println("---------client---------");
   System.out.println("请输入您想说的话:");
   str = scanner.next();
   //2.利用write写
   pw.println(str);
   pw.flush();
  }

  //3.关闭通道



  //三.关闭socket连接
  if(s!=null){
   try {
    s.close();
   } catch (IOException e) {
    System.out.println("关闭socket连接失败");
    e.printStackTrace();
   }
  }
}
}
第四步：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientReceiver2 implements Runnable{

public void run() {
  receive();

}

public void receive(){
  //一.建立socket连接
  //2.客户端申请连接
  //只是申请连接还没真正接通相当于打电话拨号对方不一定接
  Socket s = null;
  try {
   s = new Socket("localhost",9999);
  } catch (UnknownHostException e) {
   System.out.println("找不到主机,连接socket失败");
   e.printStackTrace();
  } catch (IOException e) {
   System.out.println("建立socket连接失败");
   e.printStackTrace();
  }

  //二.I/O操作
  //1.建立通道
  try {
   InputStream os = s.getInputStream();

   BufferedReader br = new BufferedReader(new InputStreamReader(os));

   //2.利用read读
   String message = br.readLine();
   System.out.println("---------client---------");
   System.out.println("服务器对您说:" + message);



   //---------------------一直说-----------------------
   while(!message.equals("88")){
    message = br.readLine();
    System.out.println("---------client---------");
    System.out.println("服务器对您说:" + message);

   }
  } catch (IOException e) {
   System.out.println("客户端读取数据失败");
   e.printStackTrace();
  }

  //3.关闭通道



  //三.关闭socket连接
  if(s!=null){
   try {
    s.close();
   } catch (IOException e) {
    System.out.println("关闭socket失败");
    e.printStackTrace();
   }
  }
}
}
第五步：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class ServerReceiver1 implements Runnable{

public void receive(){

  //一.建立socket连接
  //1.新建ServerSocket
  ServerSocket ss = null;
  try {
   ss = new ServerSocket(8888);
  } catch (IOException e) {
   System.out.println("重复的端口,请先关闭相应程序,再从新启动");
   e.printStackTrace();
  }
  Socket socket = null;
  try {
   socket = ss.accept();
  } catch (IOException e) {

   e.printStackTrace();
  }//阻塞式的傻傻的等待等待客户端申请连接

  System.out.println("有一个客户端连接");

  //二.I/O操作
  //1.建立通道
  try {
   InputStream is = socket.getInputStream();

   BufferedReader br = new BufferedReader(new InputStreamReader(is));

   //2.利用read读
   String message = br.readLine();
   System.out.println("-------------Server---------");
   System.out.println("客户端对你说:" + message);

   while(!message.equals("88")){
    //一直读
    message = br.readLine();
    System.out.println("-------------Server---------");
    System.out.println("客户端对你说:" + message);
   }
  } catch (IOException e) {
   System.out.println("服务器接收数据失败");
   e.printStackTrace();
  }


  //3.关闭通道



}

public void run() {
receive();

}
}

第六步：

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Scanner;

public class ServerSend2 implements Runnable{

public void send(){

  //一.建立socket连接
  //1.新建ServerSocket
  ServerSocket ss = null;
  try {
   ss = new ServerSocket(9999);
  } catch (IOException e) {
   System.out.println("重复的端口,请先关闭相应程序,再从新启动服务器");
   e.printStackTrace();
  }
  Socket socket = null;
  try {
   socket = ss.accept();
  } catch (IOException e) {
   System.out.println("建立socket连接失败");
   e.printStackTrace();
  }//阻塞式的傻傻的等待等待客户端申请连接

  System.out.println("有一个客户端连接");

  //二.I/O操作
  //1.建立通道
  OutputStream os = null;
  try {
   os = socket.getOutputStream();
  } catch (IOException e) {
   System.out.println("服务器端建立输出流失败");
   e.printStackTrace();
  }

  PrintWriter pw = new PrintWriter(os);

  //2.利用write写

  System.out.println("-------------Server---------");
  Scanner scanner = new Scanner(System.in);
  System.out.println("请输入您想说的话:");
  String str = scanner.next();

  pw.println(str);
  pw.flush();


  while(!str.equals("88")){
   //一直写
   System.out.println("-------------Server---------");
   System.out.println("请输入您想说的话:");
   str = scanner.next();

   pw.println(str);
   pw.flush();
  }


  //3.关闭通道



}

public void run() {
send();
}
