Java Program to Print Same Numbers on all Sides of a Square

Write a Java program to print the same numbers on all sides of a square pattern using for loop.

import java.util.Scanner;

public class sameNuminallSIdesSquare1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter the Maximum Number of a Square = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Same Numbers in all Sides of a Square");
		int i, j, k, min;
		
		for (i = 1 ; i <= rows; i++ ) 
		{
			for (j = 1 ; j <= rows; j++ ) 	
			{
				min = i < j? i:j;
				System.out.print(rows - min + 1 + " ");
			}
			for(k = rows - 1; k >= 1; k--)
			{
				min = i < k? i:k;
				System.out.print(rows - min + 1 + " ");
			}
			System.out.println();
		}
		
		for (i = rows - 1 ; i >= 1; i-- ) 
		{
			for (j = 1 ; j <= rows; j++ ) 	
			{
				min = i < j? i:j;
				System.out.print(rows - min + 1 + " ");
			}
			for(k = rows - 1; k >= 1; k--)
			{
				min = i < k? i:k;
				System.out.print(rows - min + 1 + " ");
			}
			System.out.println();
		}

Java Program to Print Same Numbers on all Sides of a Square

This Java example displays the square pattern where all sides have the same numbers using a while loop.

import java.util.Scanner;

public class sameNuminallSIdesSquare2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter the Maximum Number of a Square = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Same Numbers in all Sides of a Square");
		int i = 1, j, k, min;
		
		while (i <= rows ) 
		{
			j = 1 ;
			while( j <= rows ) 	
			{
				min = i < j? i:j;
				System.out.print(rows - min + 1 + " ");
				j++;
			}
			k = rows - 1;
			while( k >= 1)
			{
				min = i < k? i:k;
				System.out.print(rows - min + 1 + " ");
				 k--;
			}
			System.out.println();
			i++;
		}
		
		i = rows - 1 ; 
		while (i >= 1) 
		{
			j = 1 ;
			while( j <= rows ) 	
			{
				min = i < j? i:j;
				System.out.print(rows - min + 1 + " ");
				j++;
			}
			k = rows - 1;
			while( k >= 1)
			{
				min = i < k? i:k;
				System.out.print(rows - min + 1 + " ");
				 k--;
			}
			System.out.println();
			i--;
		}
	}
}
