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:
Determine the size of the square pattern based on the desired number of rows or columns.
Use nested loops to iterate through the rows and columns.
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
Input the desired size of the square pattern.
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:
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.
After printing all the rows, the hollow square pattern will be displayed.
Code
Here's an example implementation for printing a hollow square pattern of stars:
Example Output
For size = 5, the output will be:
Conclusion
Printing a hollow square pattern of stars is an interesting exercise that helps improve our understanding of nested loops, pattern generation, and logical thinking in programming. By following the approach and step-by-step solution provided in this article, we can create various hollow square patterns with stars. This exercise demonstrates the flexibility and power of loops in achieving complex patterns.
