package com.codegym.games.snake;
import com.codegym.engine.cell.*;

public class SnakeGame extends Game{
    public static final int WIDTH = 15;
    public static final int HEIGHT = 15;


   int width = 20;
   int height = 20;

   public void initialize(){
       setScreenSize(WIDTH,HEIGHT);
   }
}

class Game{
    public void setScreenSize(int a, int b){
    }
}
I have problem with "The SnakeGame class must inherit the Game class" What should I do ?
