⭐ Pattern Programs using Java

This repository contains a collection of Java Pattern Programs designed to help beginners understand loops, nested loops, and logic building in programming.

Pattern programs are one of the most common exercises in Java learning and are frequently asked in coding interviews to test logical thinking and control flow understanding. :contentReference[oaicite:0]{index=0}

🧠 About the Project

Pattern programs are used to print structured shapes or designs (like stars, numbers, or alphabets) using loops and conditions.

These programs help in:

• Understanding nested loops
• Improving problem-solving skills
• Strengthening logic building
• Preparing for coding interviews

Most pattern problems rely heavily on outer loops (rows) and inner loops (columns) to generate the desired output. :contentReference[oaicite:1]{index=1}

🛠️ Technologies Used

• Java
• Core concepts:
  • Loops (for, while)
  • Conditional statements
  • Nested loops
  • Basic syntax

---

📚 Types of Patterns Covered

This repository includes different types of pattern programs:

⭐ Star Patterns

• Right triangle
• Inverted triangle
• Pyramid
• Diamond
• Square & hollow patterns

🔢 Number Patterns

• Increasing number triangle
• Reverse number patterns
• Sequential number structures

🔤 Character Patterns

• Alphabet patterns
• Letter-based shapes

Pattern programs generally fall into these categories and are widely used for mastering Java fundamentals. :contentReference[oaicite:2]{index=2}

💻 Example Pattern

⭐ Simple Star Triangle

Java Code:

public class Pattern {
    public static void main(String[] args) {
        int n = 5;
        for(int i = 1; i <= n; i++) {
            for(int j = 1; j <= i; j++) {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}
