Java Program to Print Right Triangle of Numbers in Reverse

Write a Java program to print right triangle of numbers in reverse order using for loop.

import java.util.Scanner;

public class RightTriangleNumReverse1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Reverse Right Triangle Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Right Triangle of Numbers in Reverse");
		
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = rows ; j >= i; j-- ) 	
			{
				System.out.print(j + " ");
			}
			System.out.println();
		}
	}
}

This Java example displays the reverse ordered numbers in the right angled triangle number pattern using a while loop.

import java.util.Scanner;

public class RightTriangleNumReverse2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Reverse Right Triangle Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Right Triangle of Numbers in Reverse");
		int i = rows, j;
		
		while (i >= 1 ) 
		{
			j = rows ;
			
			while(j >= i) 	
			{
				System.out.print(j + " ");
				j--;
			}
			System.out.println();
			i--;
		}
	}
}

Java program to print right angled triangle of numbers in reverse pattern using do while loop.

import java.util.Scanner;

public class RightTriangleNumReverse3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Reverse Right Triangle Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Right Triangle of Numbers in Reverse");
		int i = rows, j;
		
		do
		{
			j = rows ;
			
			do	
			{
				System.out.print(j + " ");

			} while(--j >= i);
			System.out.println();

		} while (--i >= 1 ) ;
	}
}
