骰子滾動模擬

Question

我想知道如何讓我的骰子滾動模擬器停止，當你的總滾動是2個確定的數字之一，（例如：當你達到7或12的總滾動時滾動將停止）。這是我到目前爲止的代碼：

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

只是包裝一切有do-while循環：

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); 

或者其他類似的程度。 :)
