	public class AddFive {
		public static void main (String[] args) {

			int number = 5;  // 1st num to be accumulated
			int sum = 0;     // We've added no numbers yet

			// As long as the number is bigger than 0,
			// add the number to the sum, and decrease
			// the number by one.
			while (number > 0) {
				sum += number;
				number--;
			}

			// Display the sum
			System.out.println("The sum is: " + sum);
