java - JAVA中老虎机无限循环问题

Question

我正在编写一个基本的老虎机代码，当程序运行时它似乎陷入了无限循环。如果有人可以阐明此错误的位置，或者您会推荐一些内容。感谢所有的帮助。

public class Java_Lab_3 {
    public static void main(String[] args) {
        int endgame;  
        int slot1;
        int slot2;
        int slot3;

        Random rand =  new Random();
        Scanner keyboard = new Scanner(System.in);  

        System.out.println("Want to test your luck?");
        System.out.println("To Spin, type any positive number");
        System.out.println("To End Game, type -1 and press enter ");

        endgame = keyboard.nextInt();

        while (endgame != -1) {
            slot1 = rand.nextInt(10);
            slot2 = rand.nextInt(10);
            slot3 = rand.nextInt(10);

            System.out.println(slot1 + slot2 + slot3);
            System.out.println(endgame);

            if (slot1 == slot2 && slot1 == slot3) { // Then they have JACKPOT
                System.out.println("You've Won!");
            } else if (slot1 == slot2 || slot2 == slot3 || slot1 == slot3) { // They MATCHED 2
               System.out.println("We have twins... You've matched a pair!");
            } else {
                System.out.println("Sucks to Suck, don't quit your day job!");
            }
        }
    }
}

如果您想跳出该循环，则必须编写退出条件的可能性。例如...

while (endgame != -1) {
    System.out.print("Do you want to play again? (-1 to quit): ");
    endgame = keyboard.nextInt();
}

通过这种方式，您可以在每次掷骰后提示用户再次玩游戏。
