Write a program that generates one hundred random integers between 0 and 9 and displays the count for each number. Your program must have method that returns the counts for each number.
Hint: Use (int)(Math.random() * 10) to generate a random integer between 0 and 9. Use an array of ten integers, say count, to store the counts for the number of 0’s, 1’s, …, 9’s.

Your project description literally tells you exactly what you need to do. Create an array of ten integers. Every time you see a 0, increment array[0]. Every time you see a 1, increment array[1]. Etc.

I'm not helping you by doing this but I just wanted to have some fun so here's your solution:

public class RandomNumbers {
	
	public static void main(String[] args) {
		int[] frequency = new int[10];
		
		for(int i = 0; i < 100; i++){
			int randomNumber = generate();
			frequency[randomNumber]++;
		}
		
		printArray(frequency);
	}
	
	private static int generate(){
		return (int)(Math.random() * 10);
	}
	
	private static void printArray(int[] array){
		for(int i = 0, size = array.length; i < size; i++ ){
			System.out.println(i + " frequence -> " + array[i]);
		}
	}
	
}
