    Default Dont know where to start on this Java Code using loops!! Help Please

    Write a program to generate 100 random integers
    in the range of 0 and 99999, nd the frequency count of each digit (0, 1, 2, . . . , 9) in these numbers,
    and print a frequency histogram.

    This is what I have so far:
    import java.util.Scanner;
    public class PA6 {

    /**
    * @param args
    */
    public static void main(String[] args) {
    // TODO Auto-generated method stub

    int num;
    int freq1, freq2, freq3, freq4, freq5, freq6, freq7, freq8, freq9;
    int digit;


    num = (int)(Math.random()*99999);

    while (num > 0) {
    digit = num % 10;
    num = num / 10;


    }


    }

    }

    And what exactly does that code do? Does it compile? Does it run? What's missing from it?

    For starters,
    a) use random inside the while loop
    b) have a counter inside while loop increase till 100 and break
