java基础之使用socket进行cs通信

一、

 

 二、Myserver.java

package socket;

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

public class Myserver {
public static void main(String[] args) throws IOException{
	
	try {
		 ServerSocket serverSocket = new ServerSocket(8888);
		System.out.println(123);
		Socket socket = serverSocket.accept();
		System.out.println("客户端连接成功！");
		InputStream input = socket.getInputStream();
		BufferedReader reader = new BufferedReader(new InputStreamReader(input));
        String info = null;
        while((info = reader.readLine())!=null){
        	System.out.println("I am server! 接收到的客户端消息："+info);
        }
        socket.shutdownInput();
        OutputStream out = socket.getOutputStream();
        out.write("welcome client...".getBytes());
        socket.shutdownOutput();


	} catch (Exception e) {
		// TODO: handle exception
	}
}
}

　　三、Myclient.java

package com.example.demo;

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

public class Myclient {
    public static void main(String[] args) {
        try {
            Socket socket = new Socket("localhost",8888);
            System.out.println("客户端启动");
            OutputStream out = socket.getOutputStream();
            out.write("hello socket!".getBytes());
            socket.shutdownOutput();
            InputStream input = socket.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(input));
            String info = null;
            while((info = reader.readLine())!=null){
                System.out.println("I am client! 接收到的服务端端消息："+info);
            }
            socket.shutdownInput();
        } catch (Exception e) {
            // TODO: handle exception
        }
    }
}
