		int rows = sc.nextInt();
		
		System.out.println("The Right Pascals Triangle of Mirrored Numbers Pattern");
		int i, j, k;
		
		for (i = rows; i >= 1; i-- ) 
		{
			for (j = i; j <= rows; j++ ) 
			{
				System.out.print(j + " ");
			}
			for(k = rows - 1; k >= i; k--)
			{
				System.out.print(k + " ");
			}
			System.out.println();
		}
		
		for (i = 2; i <= rows; i++ ) 
		{
			for (j = i; j <= rows; j++ ) 
			{
				System.out.print(j + " ");

Java Program to Print Right Pascals Triangle of Mirrored Numbers Pattern

This Java program prints the right pascals triangle pattern of mirrored numbers using a while loop.

package Shapes4;

import java.util.Scanner;

public class RightPascalMirrNum2 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Right Pascals Triangle Mirrored Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("The Right Pascals Triangle of Mirrored Numbers Pattern");
		int i, j, k;
		i =rows;
		
		while(i >= 1 ) 
		{
			j = i; 
			while(j <= rows ) 
			{
				System.out.print(j + " ");
				j++;
			}
			k = rows - 1;
			while( k >= i)
			{
				System.out.print(k + " ");
				k--;
			}
			System.out.println();
			i--;
		}
		
		i = 2;
		while(i <= rows ) 
		{
			j = i; 
			while(j <= rows ) 
			{
				System.out.print(j + " ");
				j++;
			}
			k = rows - 1;
			while( k >= i)
			{
				System.out.print(k + " ");
				k--;
			}
			System.out.println();

In this Java pattern example, we used the rightpascalMirrored function to separate the for loop login and display the right pascals mirrored numbers triangle.

package Shapes4;

import java.util.Scanner;

public class RightPascalMirrNum3 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Right Pascals Triangle Mirrored Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("The Right Pascals Triangle of Mirrored Numbers Pattern");
		int i;
		
		for (i = rows; i >= 1; i-- ) 
		{
			rightpascalMirrored(rows, i);
			System.out.println();
		}
		
		for (i = 2; i <= rows; i++ ) 
		{
			rightpascalMirrored(rows, i);
			System.out.println();
		}
	}
	
	public static void rightpascalMirrored(int rows, int i) {
		for (int j = i; j <= rows; j++ ) 
		{
			System.out.print(j + " ");
		}
		for(int k = rows - 1; k >= i; k--)
		{
			System.out.print(k + " ");
		}
	}
}
