java,刚刚上路不久卡了

import java.util.*;

System.out.println("Game is over.");
break;//游戏结束，终止循环
}else{
//都没猜到，继续
System.out.println("players will have to try again.");
}
}

}

public class GameLauncher{
public static void main(String[]args){
GuessGame game=new GuessGame();
game.startGame();
}
}

这看不懂好像是类不同，书上没说清

class Player
static class GameLauncher
同一个文件下 这里类修饰名要变

3个类是写在一个文件里的不，如果是，把除了GameLauncher类，其他2个类的public 去掉
