How can i put my class in the client in socket programming?

Question

I made a game similar to Flappy Bird by using JavaFX. Now I want to play it by using localhost IP. How can I move the class in FlappyBird to the client so that the flappybird becomes the client?

also how can we make multiple clients using this? This code is a simple one i made with simple concept behind it but what i don't understand is how can i make a class as in a game of flappy bird in the socket programming. How do i implement everything from the flappy bird to the client so the client becomes a flappy bird object

Client:

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


public class FlappyClient 
{ 
    // initialize socket and input output streams 
    private Socket socket            = null; 
    private DataInputStream  input   = null; 
    private DataOutputStream out     = null; 
  
    // constructor to put ip address and port 
    public FlappyClient(String address, int port) 
    { 
        // establish a connection 
        try
        { 
            socket = new Socket(address, port); 
            System.out.println("Connected"); 
  
            // takes input from terminal 
            input  = new DataInputStream(System.in); 
  
            // sends output to the socket 
            out    = new DataOutputStream(socket.getOutputStream()); 
        } 
        catch(UnknownHostException u) 
        { 
            System.out.println(u); 
        } 
        catch(IOException i) 
        { 
            System.out.println(i); 
        } 
  
        //=============
        // close the connection 
        try
        { 
            input.close(); 
            out.close(); 
            socket.close(); 
        } 
        catch(IOException i) 
        { 
            System.out.println(i); 
        } 
    } 
  
    public static void main(String args[]) 
    { 
        FlappyClient client = new FlappyClient("localhost", 5000); 
    } 
}

**The flappy bird class is too big. Lets call it FlappyBird I want to make this flappybird a client for the server**

I have found the answer
