Java Program to Print Right Arrow Number Pattern

Write a Java program to print right arrow number pattern using for loop.

import java.util.Scanner;

public class RightArrowNumber1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		int i, j;
		
		System.out.print("Enter Right Arrow Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Right Arrow Numbers Pattern");
		
		for (i = 1 ; i <= rows; i++ ) 
		{
			for (j = 1 ; j <= rows; j++ ) 
			{
				if(j < i) {
					System.out.print(" ");
				}
				else {
					System.out.print(j);
				}
			}
			System.out.println();
		}
		
		for (i = 1 ; i < rows; i++ ) 
		{
			for (j = 1 ; j <= rows; j++ ) 
			{
				if(j < rows - i) {
					System.out.print(" ");
				}
				else {
					System.out.print(j);
				}
			}
			System.out.println();
		}
	}

Java Program to Print Right Arrow Number Pattern

This is another way of of writing a Java program to display the right arrow pattern of numbers using a while loop.

import java.util.Scanner;

public class RightArrowNumber2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		int i, j, k;
		
		System.out.print("Enter Right Arrow Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Right Arrow Numbers Pattern");
		
		for (i = 1 ; i <= rows; i++ ) 
		{
			for (j = 1 ; j < i; j++ ) 
			{
				System.out.print(" ");
			}
			for (k = i ; k <= rows; k++ ) 
			{
				System.out.print(k);
			}
			System.out.println();
		}
		
		for (i = rows - 1 ; i >= 1; i-- ) 
		{
			for (j = 1 ; j < i; j++ ) 
			{
				System.out.print(" ");
			}
			for (k = i ; k <= rows; k++ ) 
			{
				System.out.print(k);
			}
			System.out.println();
		}
	}
}
