简单实现Socket编程代码

1. 本程序只实现单向发送就是服务器向客户端发送信息（如果你想两边都可以互相发送就百度查找，当时我自己也是慢慢摸索出来的）
2. 建议用idea编译器
3. 服务器代码

package Socket;

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

public class Service {

    public static void main(String[] args) throws Exception {

        ServerSocket serverSocket = new ServerSocket(8080);//在本机绑定到指定的端口，并且侦听客户端请求。

        Socket accept = serverSocket.accept();//接收请求，建立socket对象
        PrintWriter printWriter = new PrintWriter(accept.getOutputStream());

        while (true){
            Scanner input = new Scanner(System.in);
            String msg = input.nextLine();
            printWriter.println(msg);
            printWriter.flush();
            if (msg.equals("拜拜")) break;
        }

        printWriter.close();
        accept.close();
        serverSocket.close();
    }

}
           

1. 客户端代码

package Socket;

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

public class Client {

    public static void main(String[] args) throws Exception {

        Socket socket = new Socket("localhost", 8080);//首先你得得到本机端口和端口号
        InputStream inputStream = socket.getInputStream();//创建字节输入流接收信息

        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));//创建字符流接收服务器发来文本

        while (true){//顺环是为了持续接收信息

            String msg = bufferedReader.readLine();
            System.out.println(msg);

            if (msg.equals("拜拜")) break;//当服务器发给用户拜拜后就退出程序
        }

        bufferedReader.close();//以下三个是关闭相关流
        inputStream.close();
        socket.close();
    }

}
