多线程实现实例-简单的聊天小程序TCP编程尝试

运用TCP编程，实现一个从客户端到服务端多线程聊天的功能。

获取信息线程的代码

Get.java

package com.xyq.HW;

import java.io.BufferedReader;

import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Socket;


public class Get extends Thread{
    private Socket socket;
    Get(Socket socket){
        this.socket = socket;
    }

    @Override
    public void run() {
        while(true){
            try {
                InputStream is = socket.getInputStream();
                BufferedReader br = new BufferedReader(new InputStreamReader(is));
                String content = br.readLine();
                System.out.println("发送的内容是"+content);

            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }
}

发送信息线程的代码

Send.java

package com.xyq.HW;

import java.io.*;
import java.net.Socket;
import java.util.Scanner;

public class Send extends Thread{
    Scanner sc = new Scanner(System.in);
    private Socket socket;

    Send(Socket socket){
        this.socket = socket;
    }
    @Override
    public void run() {
        while(true){

            try {
                OutputStream os = socket.getOutputStream();
                BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os));
                String content = sc.nextLine();
                bw.write(content);
                bw.newLine();
                bw.flush();

            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }

客户端代码Client.java

package com.xyq.HW;

import java.net.Socket;

public class Client {
    public static void main(String[] args) throws  Exception {
        Socket socket = new Socket("localhost",9999);

        Get rt = new Get(socket);
        rt.start();
        //4.启动第二个线程
        Send st = new Send(socket);
        st.start();

    }
}

服务器代码Server.java

package com.xyq.HW;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class Server  {
public static void main(String[]args) throws IOException {
        //1.创建连接
        ServerSocket ss = new ServerSocket(9999);
        //2.等待客户端连接
        Socket socket = ss.accept();
        //3.客户端连接后启动第一个线程
        Get rt = new Get(socket);
        rt.start();
        //4.启动第二个线程
        Send st = new Send(socket);
        st.start();

        }
}
