Java Саймон говорит

В настоящее время у меня есть GUI, созданный для игры simon, единственная проблема, с которой я сталкиваюсь, - это реализация логики игры (мой текущий код будет генерировать последовательность и отображать ввод пользователя, но не сохранит сгенерированную последовательность или сравните его со входом). Я знаю, что мне нужно использовать либо очередь, либо стек, но я не могу понять, как реализовать любой из них, чтобы создать рабочую игру.

Кто-нибудь может помочь, вот что я получил до сих пор:

Driver:

import javax.swing.JFrame;

public class Location 
{
   public static void main (String[] args) 
   {
      JFrame frame = new JFrame ("Location");
      frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(new LocationPanel());
      frame.pack();
      frame.setVisible(true);
   }
}
