骰子滚动模拟

Question

我想知道当你的总掷骰是2个特定数字中的一个时，我怎么能让我的骰子滚动模拟器停止（例如：滚动将在你达到7或12的总滚动时停止）。 到目前为止，这是我的代码：

public class RollDice {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        int dice1;   // First Dice.
        int dice2;   // Second Dice.
        int total;   // Sum of the two rolls. 

        dice1 = (int)(Math.random()*6) + 1;
        dice2 = (int)(Math.random()*6) + 1;
        total = dice1 + dice2;

        System.out.println("Your first roll is " + dice1);
        System.out.println("Your second roll is  " + dice2);
        System.out.println("Your complete roll is " + total);

    }  

}  

Answer 1

只需使用do-while循环包装所有内容：

int total;   // Sum of the two rolls. 
do {
    int dice1;   // First Dice.
    int dice2;   // Second Dice.

    dice1 = (int)(Math.random()*6) + 1;
    dice2 = (int)(Math.random()*6) + 1;
    total = dice1 + dice2;

    System.out.println("Your first roll is " + dice1);
    System.out.println("Your second roll is  " + dice2);
    System.out.println("Your complete roll is " + total);
} while (total != 7 && total != 12);

或者那种程度的东西。 :)
