Pattern Printing System

A console-based Pattern Printing System built using Java. The project allows users to explore and print different star, number, alphabet, and advanced patterns by selecting a category and pattern from the menu. It also includes input validation, selection previews, and a project report that tracks the patterns printed during the session.

Features

• 4 Pattern Categories
• 8 Star Patterns
• 6 Number Patterns
• 5 Alphabet Patterns
• 5 Advanced Patterns
• Input validation for menu choices
• Input validation for rows and columns
• Pattern selection preview
• Ability to print multiple patterns in one session
• Project report showing the total number of patterns printed and category-wise counts

Concepts Used

• Methods
• Method Overloading
• Loops
• Nested loops
• Conditional statements
• Switch expressions
• Scanner for user input
• Input validation
• Breaking a larger program into smaller methods

How It Works

1. The program displays the pattern categories.
2. The user selects a category.
3. The program displays the patterns available in that category.
4. The user selects a pattern.
5. The program asks for the required number of rows or columns.
6. A selection preview is displayed.
7. The selected pattern is printed in the console.
8. The user can choose to print another pattern.
9. At the end, a project report displays the total number of patterns printed along with category-wise counts.

How to Run

1. Clone this repository.
2. Open the project in IntelliJ IDEA or any Java-compatible IDE.
3. Make sure Java is installed and configured.
4. Run PatternPrintingSystem.java.
5. Follow the instructions displayed in the console.
