Exciting array review problems

public class Main {
    public static void main(String[] args) {
        int[] nums = new int[7];
        fiboize(nums);
        printInts(nums);
    }
}

Running the above code does the following:

Creates an array of seven integers

Assigns the first seven Fibonacci numbers into the array

Prints out the contents of the array

Write the methods fiboize and printInts such that they will work on any size array.

Now consider the following code:

public class Main {
    public static void main(String[] args) {
        int[][] nums = new int[4][6];
        populate(nums);
        printInts(nums);
    }
}

Write the method populate that sets each elements of nums to the product of the indices (i.e., nums[2][3] should be 6 because 2*3 = 6, nums[0][anything] should be 0 because 0*anything = 0).

Then write another methd called printInts that takes a two-dimensional array of ints and prints them all out.
