连接到套接字服务器

Question

我制作了较差的套接字服务器。如果我想从邻居计算机连接到服务器，该怎么办？他只需要我的client.java类，还是都需要server.java？

import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {

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

        ServerSocket s = new ServerSocket(4031);
        Socket ss = s.accept();
        System.out.println("Connected");
        DataInputStream dout = new DataInputStream(ss.getInputStream());
        //BufferedReader br = new BufferedReader(new 
    InputStreamReader(System.in));
        while(true) {
            String yoo = dout.readUTF();
            System.out.println("Client: "+yoo);
            if(yoo.equalsIgnoreCase("Exit")) {
                break;
            }
        }
        ss.close();
    }
}
