JAVA基础之网络编程

一：服务端

需要先设置服务器端口，开启服务端，等待客户端连接请求。若连接成功，服务端会获得Socket对象，用于交互信息

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

/**

 */
public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = new ServerSocket(1234);
        System.out.println("端口号为1234");
        Socket socket = serverSocket.accept();

        new SendThread(socket).start();
        new RecieveThread(socket).start();
    }
}

 

二：客户端

需要知道服务器的端口和IP地址，对其发送连接请求

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

/**

 */
public class Client {
    public static void main(String[] args) throws IOException {
        Socket socket = new Socket("127.0.0.1",1234);
        new SendThread(socket).start();
        new RecieveThread(socket).start();
    }
}
