java socket测试

以下是一个简单的Java Socket测试的例子：

1.服务端代码：

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(8888);
        System.out.println("服务端已启动，等待客户端连接...");
        Socket socket = serverSocket.accept();
        System.out.println("客户端已连接，客户端地址：" + socket.getInetAddress().getHostAddress());
        socket.close();
        serverSocket.close();
    }
}

2.客户端代码：

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

public class Client {
    public static void main(String[] args) throws IOException {
        Socket socket = new Socket("localhost", 8888);
        System.out.println("客户端已连接到服务端，服务端地址：" + socket.getInetAddress().getHostAddress());
        socket.close();
    }
}
