Java Program to Print Consecutive Numbers Right Triangle Rows

Write a Java program to print consecutive numbers in right angled triangle rows using for loop.

import java.util.Scanner;

public class ConsecutiveNumberinrows1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Consecutive Row Numbers Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Consecutive Row Numbers Right Triangle Pattern");

		for (int i = 1 ; i <= rows; i++ ) 
		{
			int val = i;
			
			for (int j = 1 ; j <= i; j++ ) 	
			{
				System.out.print(val + " ");
				val = val + rows - j;
			}
			System.out.println();
		}
	}
}
