Question

我的程序无效！我需要它随机滚动两个骰子，计算卷数，直到达到蛇眼（2个）我觉得我很亲密，但是我的程序只会滚动一次，而不是很多次，直到滚动两次。

我得到的输出被计为一个骰子卷的无限循环！

import java.io.*;

public class PA 
{
    public static void main (String [] args) 
    {
        int count = 0;
        int die1 = (int)(Math.random()*6)+1;
        int die2 = (int)(Math.random()*6)+1;
        int sumDie = die1+die2;    
        do 
        {
            System.out.println ("You rolled a:" + die1);
            System.out.println ("You rolled a:" + die2);
            System.out.println ("This is roll number:" + count);
            count = count + 1;
        } 
        while (sumDie > 2); 
        {
            System.out.println ("You rolled:" + die1);
            System.out.println ("You rolled:" + die2);
            System.out.println ("This is roll number:" + count):
            count++
        }
        if (die1 == 1 && die2 == 1);
        System.out.println ("Congratulations...Snake Eyes");
    }
}

您需要将掷骰子的代码移动到循环内部。并且，不需要那段时间后的代码块。最后if - 首先它因为分号而无效（没有身体）。其次，不需要，因为while条件确保了这种情况。

public static void main (String [] args) 
{
    int count = 0;
    int die1, die2;
    do 
    {
        // New roll each time
        die1 = (int)(Math.random()*6)+1;
        die2 = (int)(Math.random()*6)+1;

        count = count + 1;
        System.out.println ("You rolled a:" + die1);
        System.out.println ("You rolled a:" + die2);
        System.out.println ("This is roll number:" + count);
    } while (die1 + die2 > 2);

    System.out.println ("Congratulations...Snake Eyes");
}

做循环Java语言吗？
