Java creates server-side serverSocket and client-side socket

Create server-side serverSocket

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;/**
 * 服务端
 * @author Administrator
 *
 */public class Server {

    public static void main(String[] args) throws IOException {        //创建一个服务器端socket，指定绑定的端口号，并监听此端口
        ServerSocket serverSocket = new ServerSocket(8888);        //调用accept()方法开始监听，等待客户端的连接
        System.out.println("**********服务器即将启动，等待客户端的连接*************");
        Socket socket = serverSocket.accept();        //获取输入流，并读取客户端信息
        InputStream inp = socket.getInputStream();        //把字节流转换成字符流
        InputStreamReader isr = new InputStreamReader(inp);        //为字符流增加缓冲区
        BufferedReader bfr = new BufferedReader(isr);
        String info = null;        while((info=bfr.readLine())!=null){//循环读取数据
            System.out.println("客户已连接，报文内容："+info);
        }
        socket.shutdownInput();//关闭输入流
        //向客户端传递的信息
        OutputStream ots = socket.getOutputStream();
        PrintWriter pw = new PrintWriter(ots);
        pw.write("欢迎使用");
        pw.flush();        //关闭资源
        pw.close();
        ots.close();
        bfr.close();
        isr.close();
        inp.close();
        socket.close();
        serverSocket.close();

    }

}

Client-side socket

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.Socket;import java.net.UnknownHostException;/**
 * 客户端
 * @author Administrator
 *
 */public class Client {

    public static void main(String[] args) {        try {            //创建一个客户端socket
            Socket socket = new Socket("localhost",8888);            //向服务器端传递信息
            OutputStream ots = socket.getOutputStream();
            PrintWriter pw = new PrintWriter(ots);
            pw.write("服务器你好！");
            pw.flush();            //关闭输出流
            socket.shutdownOutput();            //获取服务器端传递的数据
            InputStream is = socket.getInputStream();
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String info = null;            while((info=br.readLine())!=null){
                System.out.println("服务器返回报文："+info);
            }            //关闭资源
            br.close();
            isr.close();
            is.close();
            pw.close();
            ots.close();
            socket.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

Server-side output:

**********服务器即将启动，等待客户端的连接*************客户已连接，报文内容：：服务器你好！

Client-side output ：

服务器返回报文：欢迎使用
