一个简单的JAVA服务器-客户端模型-tcp

package com.sxt.tcp;

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

public class Server {
    public static void main(String[] args) throws IOException {
        System.out.println("----Server----");

        ServerSocket server = new ServerSocket(8888);

        Socket client = server.accept();
        System.out.println("一个客户建立连接");

        DataInputStream dis = new DataInputStream(client.getInputStream());

        String recv = dis.readUTF();
        System.out.println(recv);

        dis.close();
        client.close();
        server.close();
    }
}

package com.sxt.tcp;

import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;

public class Client {
    public static void main(String[] args) throws UnknownHostException, IOException {
        System.out.println("----Client----");

        Socket client = new Socket("localhost",8888);

        DataOutputStream dos = new DataOutputStream(client.getOutputStream());

        String data = "你好呀,TCP";
        dos.writeUTF(data);
        dos.flush();

        dos.close();
        client.close();
    }
}

结果
