多线程(三)_服务端和客户端单线程互动_2、建立客户端和服务端程序(先单线程,后多线程);-优快云博客

本文提供了一个简单的Java网络编程示例，包括服务端与客户端的实现。服务端监听23600端口，接收客户端发来的消息并反馈已接收的信息。客户端连接到本地服务端后，可以输入消息发送到服务端，当输入'end'时结束通信。

服务端：

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

public class Server {
	
	private static BufferedReader br = null;
	private static ServerSocket ss = null;
	private static PrintWriter ps = null;

	public static void main(String[] args) throws Exception{
		//创建服务端对象 
		ss = new ServerSocket(23600);
		Socket socket = ss.accept();
		boolean flag = true;
		br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		//
		ps = new PrintWriter(socket.getOutputStream());
		//不断的读取信息 
		while(flag){
			
			String msg = br.readLine();
			System.out.println(msg);
			if(msg.equals("end")){
				flag = false;
			}
			//向客户端发送信息 
			ps.print("has receive...\n");
			ps.flush();
			
		}
		socket.close();
		

	}

}

客户端：；

package ext3;

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

public class Client {
	private static BufferedReader br = null;
	private static PrintWriter pw = null;
	private static BufferedReader brs = null;

	public static void main(String[] args) throws Exception{
		Socket socket = new Socket("127.0.0.1", 23600);
		br = new BufferedReader(new InputStreamReader(System.in));
		pw = new PrintWriter(socket.getOutputStream());
		
		brs = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		boolean flag = true;
		while(flag){
			String msg = br.readLine();
			pw.print(msg+"\n");
			pw.flush();
			if(msg.equals("end")){
				flag = false;
			}
			System.out.println(brs.readLine());
		}
		socket.close();
	}

}
