Arrays - counting occurence

Question

Hello everyone :)
A practical at college is requiring me to create a program that simulates throwing 3 dice a total of 5000 times and for it to tally the number of times that all possible answers have occurred. For example, with 3 dice the lowest you can get is 3 (three 1's) and highest, 18 (three 6's). Roll the three dice, see which of the 16 different outcomes (3-18) you have, and add 1 to the total number of occurrences that outcome has produced. After 5000 throws, I will need to see which outcome happened most often. I've been told I must use an array for counting the occurrences and it's the array part which is confusing me.
Implementing the 3 dice and a method that simulates them being thrown was easy but I just do not have a clue how to:
1) get it to be done 5000 times and
2) the outcomes be tallied
Heres the code I have so far..
import java.lang.Math;
public class ThreeDice
    public static int throwDie()
            double x = Math.random();
            double x2 = Math.random();
            double x3 = Math.random();
            x = (x * 6.0) + 1.0;
            x2 = (x2 * 6.0) +1.0;
            x3 = (x3 * 6.0) +1.0;
            int dice1 = (int)Math.floor(x);
            int dice2 = (int)Math.floor(x2);
            int dice3 = (int)Math.floor(x3);
            return dice1 + dice2 + dice3;
    public static void main(String args[])
    }the throwDie method has to be used in main method but I'm stuck as for what to do next I'm afraid.

Answer 1

Hello Looce and thank you for the welcome,
Using my (very limited) knowledge I've managed to get the first part done (roll the 3 dice 5000 times) and for now I've just set it to print all 5000 results and alas it indeed prints 5000 results.
The second part though I'm still stuck on, I was hoping google would be my savior but sadly not this time.
I should have probably said in my first post that I'm a complete beginner for Java but with it being used both this year and next year for college, I hope to be fairly skilled in the use of it one day :)
An update of the code:
import java.lang.Math;
public class ThreeDice
    public static int throwDie()
            double x = Math.random();
            double x2 = Math.random();
            double x3 = Math.random();
            x = (x * 6.0) + 1.0;
            x2 = (x2 * 6.0) +1.0;
            x3 = (x3 * 6.0) +1.0;
            int dice1 = (int)Math.floor(x);
            int dice2 = (int)Math.floor(x2);
            int dice3 = (int)Math.floor(x3);
            return dice1 + dice2 + dice3;
    public static void main(String args[])
            for(int i=0; i<5000; i++){
                System.out.println(throwDie());
    }
