		int evenRows=0;
		int oddRows=0;
		for (int i = 1; i <= n; i++) {
			if (i % 2 == 0) {
				sumEvenNumbers += i;
				evenRows++;
			}
			if (i % 2 != 0) {
				sumOddNumbers += i;
				oddRows++;
			}
		}
		System.out.println("\nSum of even numbers = " + sumEvenNumbers);
		System.out.println("Sum of odd numbers = " + sumOddNumbers);
		System.out.println("The number of even rows = " + evenRows);
		System.out.println("The number of odd rows = " + oddRows);
		keyBoard.close();
