Java Program to Print Square of Right Increment Numbers Pattern

Write a Java program to print square of right increment numbers pattern using for loop.

package Shapes3;

import java.util.Scanner;

public class SquareRightincNum1 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Square of Right Increment Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Square of Increment Numbers from Right Side");
		
		for (int i = 1; i <= rows; i++ ) 
		{
			for (int j = 1; j <= rows - i; j++ ) 
			{
				System.out.print(1 + " ");
			}
			for(int k = 1; k <= i; k++) 
			{
				System.out.print(i + " ");
			}
			System.out.println();
		}
	}
}

This Java program prints the square pattern of increment numbers from right side using a while loop.

package Shapes3;

import java.util.Scanner;

public class SquareRightincNum2 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Square of Right Increment Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Square of Increment Numbers from Right Side");
		int j, k, i = 1;
		
		while( i <= rows) 
		{
			j = 1;
			while(j <= rows - i ) 
			{
				System.out.print(1 + " ");
				j++;
			}
			
			k = 1;
			while( k <= i) 
			{
				System.out.print(i + " ");
				k++;
			}
			System.out.println();
			i++;
		}
	}
}

Enter Square of Right Increment Numbers Rows = 9
Square of Increment Numbers from Right Side
1 1 1 1 1 1 1 1 1 
1 1 1 1 1 1 1 2 2 
1 1 1 1 1 1 3 3 3 
1 1 1 1 1 4 4 4 4 
1 1 1 1 5 5 5 5 5 
1 1 1 6 6 6 6 6 6 
1 1 7 7 7 7 7 7 7 
1 8 8 8 8 8 8 8 8 
9 9 9 9 9 9 9 9 9 

In this Java example, we created a squareIncNum function that will display the square pattern of increment numbers from the right hand side.

package Shapes3;

import java.util.Scanner;

public class SquareRightincNum3 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Square of Right Increment Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Square of Increment Numbers from Right Side");	
		squareIncNum(rows);
		
	}
	
	public static void squareIncNum(int rows)
	{
		for (int i = 1; i <= rows; i++ ) 
		{
			for (int j = 1; j <= rows - i; j++ ) 
			{
				System.out.print(1 + " ");
			}
			for(int k = 1; k <= i; k++) 
			{
				System.out.print(i + " ");
			}
			System.out.println();
		}
	}
}

Enter Square of Right Increment Numbers Rows = 5
Square of Increment Numbers from Right Side
1 1 1 1 1 
1 1 1 2 2 
1 1 3 3 3 
1 4 4 4 4 
5 5 5 5 5
