Question

我一直在研究我的java类的问题，我们必须创建3个老虎机对象并播放它们，直到我们用完了四分之一。第一台机器每40次付30个季度就玩了30次。第二台机器每85次播放60次，播放次数为10次，第三台机器每播放10次，播放次数为11次，播放次数为9次。然后我计算了机器播放的次数，直到它们没钱了。在我运行该程序之后，它说它播放机器18770次，但是，我将它与我的其他同学进行比较，并且它们的输出在每个值33569时是不同的。这是我的代码：

 import java.util.Scanner;
 public class Slots {
 public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    Slotmachines game1 = new Slotmachines(30, 40);
    Slotmachines game2 = new Slotmachines(60, 85);
    Slotmachines game3 = new Slotmachines(11, 10);
    int quarters;
    int plays = 0;
    int play1, play2, play3;
    System.out.println("How many quarters are in the jar: \n");
    quarters = input.nextInt();
    System.out.println("How many times has the first machine been played: \n");
    play1 = input.nextInt();
    play1 = game1.setCounter(play1);
    System.out.println("How many times has the second machine been played: \n");
    play2 = input.nextInt();
    play2 = game2.setCounter(play2);
    System.out.println("How many times has the third machine been played: \n");
    play3 = input.nextInt();
    play3 = game3.setCounter(play3);
    while(quarters != 0){
        plays++;
        quarters--;
        game1.game();
        quarters += game1.game();
        if(quarters != 0){
            plays++;
            quarters--;
            game2.game();
            quarters += game2.game();
        }
        if(quarters != 0){
            plays++;
            quarters--;
            game3.game();
            quarters += game3.game();
        }
    }
    System.out.println("Marge played a total of " + plays + " times");



}

}

这是第二堂课：

 public class Slotmachines {
    int payOut;
   int playLimit;
   int counter;



   public Slotmachines(int payOut, int playLimit) {
       this.payOut = payOut;
       this.playLimit = playLimit;
   }


   public void setPayOut(int payOut) {
       this.payOut = payOut;
   }

   public int getPayOut() {
       return payOut;
   }

   public void setPlayLimit(int playLimit) {
       this.playLimit = playLimit;
   }

   public int getPlayLimit() {
       return playLimit;
   }

   public int setCounter(int counter){
       this.counter = counter;
       return this.counter;
   }

   public int getSlotCounter() {
       return counter;
   }


   public int game() {
       int result = 0;
       counter++;
       if (counter >= playLimit) {
           counter = 0;
           result = payOut;
       }
       return result;
}
}

这是我的输出：

罐子里有多少个季度：

5000

第一台机器播放了多少次：

30

第二台机器播放了多少次：

10

第三台机器播放了多少次：

9

玛奇总共打了18770次

由于播放的次数是18770，我想知道它为什么会这样，为什么/如何使输出等于33569。

Answer 1

在循环的每次迭代中，您正在每台机器播放两次

game2.game();
quarters += game2.game();

当您调整四分之一并为其中一个增加游戏时。
