			System.out.print("Enter the value of item number " + (i + 1) + ": ");
			numbers[i] = keyBoard.nextInt();
		}


		Random rand = new Random();


		for (int i = 0; i < numbers.length; i++) {
			int randomIndexToSwap = rand.nextInt(numbers.length);
			int temp = numbers[randomIndexToSwap];
			numbers[randomIndexToSwap] = numbers[i];
			numbers[i] = temp;
