How to separate values from an array into different array based on odd and even in java? [duplicate]

I want to sort my array 'arrSort' auto generated with random value upto 2000 into 2 different arrays, 'arrEven' and 'arrOdd' and then print our the values with the array index number too for the odd and even arrays similar to the print output of the arrSort array.

I've had a look at this question Array even & odd sorting, and it's helpful, but doesn't address sorting an array with randomly generated variables and the 'for' loop used in a way that increasingly considers values in an array since the value are not already predefined.

I've been stuck at this for so long. Plz help.

public class ArraySortingOddEven
{

    public static void main(String[] args)
    {
        Random rand = new Random();
        int upperbound = 2000;

        int n = 0;

        // Create arrays (indexed).
        int arrSort[];
        arrSort = new int[20];

        int arrEven[] = new int[10];

        int arrOdd[] = new int[10];

        {// Assign random numbers.
            for (n = 0; n <= arrSort.length - 1; n++)
            {
                arrSort[n] = rand.nextInt(upperbound);

                System.out.println("random value assigned for arrsort[" + n + "] is " + arrSort[n]);
            }
        }

        System.out.println("");

        for (n = 0; n < arrSort.length; n++)
        {

            if (arrSort[n] % 2 == 0)
            {
                arrSort[n] = arrEven[n];
            } else
            {
                arrSort[n] = arrOdd[n];
            }

            n++;

        }

        for (n = 0; n < arrSort.length-1; n++)
        {
            System.out.println("Numbers in the even array are " + arrEven[n]);
            n++;
        }

        System.out.println("");

        for (n = 0; n < arrSort.length-1; n++)
        {
            System.out.println("Numbers in the odd array are " + arrOdd[n]);
            n++;
        }

    }

}

Here is the console.
