java - 骰子模拟寻找正确的点

Question

how many dice dots do u want?
6
try 1 : 2
try 2 : 4
try 3 : 5
try 4 : 6
In 4 try's u found 6 dots

这就是我想要获得的输出，但似乎找不到如何实现。

System.out.println("how many dice dots do u want?");
int dots = s.nextInt();
int dots2 = (int) (6 * Math.random()) + 1;

这就是我所拥有的。我现在尝试了 for 循环，但似乎不起作用。有人可以帮助我吗？

您可以通过以下方式实现您想要的:

Scanner scan = new Scanner (System.in);

    int randomValue = 0;   //this is the random value that'd be autogenerated in each loop
    int counter = 1;    //this represents the number of trials

    System.out.println("how many dice dots do u want?");
    int dotsWanted = scan.nextInt();

    while(randomValue != dotsWanted){
        randomValue = (int) (6 * Math.random()) + 1;
        counter++;
    }

    System.out.printf("In %d trials, %d dots were found\n", counter, dotsWanted);

我希望这会有所帮助......快乐编码!
