好像我的java代码卡在某个循环中

Question

import java.util.Random;

public class GameOfNim

这是我的nim类游戏

public class Project5
{
    public static void main(String args[]) 
    {
      String k = "yes";
      String str;

        Scanner console = new Scanner(System.in);
        System.out.print("Enter the minimum number of marbles in your pile: ");
        int min = console.nextInt();

        System.out.print("Enter the maximum number of marbles in your pile: ");
        int max= console.nextInt();
        GameOfNim game = new GameOfNim(min, max);

        game.play();

      System.out.println( " Thank you and good bye!");
    }
}

这是我的驱动程序类

由于某些原因每次我运行它它一直到它说“计算机先行”然后没有其他事情发生。我假设它陷入了一个循环，但我似乎无法找出原因。任何帮助将不胜感激
