Question

I have this code:

public static int MAX;
public static int MIN;


public static void startGame(){

    MIN = -1;

    MAX = 1;

    int[] randomGridVals = new int[ROWS*COLUMNS];

    fill(randomGridVals);

    System.out.println(Arrays.toString(randomGridVals));

    <MORE CODE>
}

private static void fill(int[] randomGridVals) {

    for(int i = 0 ; i < randomGridVals.length; i++)
    {
        int rnd = MIN + (int)(Math.random() * ((MAX - MIN) + 1));

        randomGridVals[i] = rnd;
    }

}

I expect that the array is passed by reference and the array have random values in it however when I try to print it its empty. Why is this happening ?

Answer 1

Hard to say for sure from the code you have provided. I would check the value of ROWS*COLUMNS. That is probably 0 and thus you create a 0 sized array.
