Printing A Hollow Square Pattern Of Stars

Introduction

Creating patterns with stars is a common exercise in programming. In this article, we will focus on printing a hollow square pattern of stars using java. We will discuss the understanding of the pattern, the approach to constructing it, and provide a step-by-step solution with sample code.

Understanding the Hollow Square Pattern of Stars

A hollow square pattern is a pattern that consists of rows and columns of stars, forming a square shape with empty spaces in the middle. The outer border is made up of stars, while the inner area remains empty.

Approach 

To print a hollow square pattern of stars, we can follow the following approach:

1. Determine the size of the square pattern based on the desired number of rows or columns.

2. Use nested loops to iterate through the rows and columns.

3. Print the desired number of stars in each row, taking into account the special cases for the outer and inner rows.

Step-by-Step Solution

1. Input the desired size of the square pattern.

2. Use a loop to iterate through each row from 1 to the desired size: 

a. Use another loop to iterate through each column from 1 to the desired size:

2. • For the first and last rows (outer rows), print a star for each column.

   • For the remaining rows (inner rows), print a star for the first and last column, and empty spaces for the other columns.

3. After printing all the rows, the hollow square pattern will be displayed.
