在运行server2文件后，在浏览器中输入www.localhost:9998/后
浏览器得不到服务器所发送的字符串，服务器也没报错，请问一下是什么原因？

package socket;

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

public class server2 {
public static void main(String[] args) throws Exception {

    ServerSocket serverSocket = new ServerSocket(9998);


    System.out.println("=====我的 web 服务在 9998 端口监听=====");

    Socket socket = serverSocket.accept();

    OutputStream outputStream = socket.getOutputStream();

    outputStream.write("hello world 9998~".getBytes());

    outputStream.close();
    socket.close();

    serverSocket.close();
}

}
