Code example to output the triangular number sequence.

import java.util.Scanner;

class TriangularNumbers {
	private static void triangularAlgorithm(int n) {
		int triangular = 0;

		for (int i = 1; i <= n; i++) {
			triangular = triangular + i;

			System.out.println(triangular);
		}
	}

	public static void main(String[] args) {
		Scanner reader = new Scanner(System.in);

		System.out.print("Enter the quantity of triangular numbers? ");
		int quantitiy = reader.nextInt();
		reader.close();

		triangularAlgorithm(quantitiy);
	}
}
