骰子滚动模拟

Question

So I am lost. This is the goal:

Ask how many times to roll one six-sided dice. Randomly roll this dice. Print out how many times each number between one and six appeared

Is this loop thing on the right track? What should I begin with I'm really confused sorry

while(dice > 0)
{
    rolldice = gen.nextInt(6) + 1;  //(1-6)
    if (rolldice == 1)
    {
        one++;
    }
    else if (rolldice == 2)
    {
        two++;
    }
    else if (rolldice == 3)
    {
        three++;
    }
    else if (rolldice == 4)
    {
        four++;
    }
    else if (rolldice == 5)
    {
        five++;
    }
    else if (rolldice == 6)
    {
        six++;
    }
}

Answer 1

Im assuming the dice integer is the input from the user. If you decrement dice each time you iterate, you will roll the dice(go through the loop) as many times as the user asked.

Not sure if you have implemented it so that the user can input a number of dicerolls yet, if thats what you need help with take a look at Scanner.

Answer 2

Scanner in = new Scanner(System.in);
Random gen = new Random();
int rollDice;
int one = 0, two = 0, three = 0, four = 0, five = 0, six = 0;

System.out.println("How many die do you want to roll: ");

int dice = in.nextInt();

while(dice > 0)
{
    rolldice = gen.nextInt(6) + 1;  //(1-6)
    if (rolldice == 1)
    {
        one++;
    }
    else if (rolldice == 2)
    {
        two++;
    }
    else if (rolldice == 3)
    {
        three++;
    }
    else if (rolldice == 4)
    {
        four++;
    }
    else if (rolldice == 5)
    {
        five++;
    }
    else if (rolldice == 6)
    {
        six++;
    }
    dice--;
}

Now just print out the variables and you are done!

I could also do this with a switch statement, but I'll let you figure out how to convert if thats what you want to use.
