Hey there! 👋
I’ve recently started diving into design patterns, and I’ll be honest—I’m not an expert yet. But that’s exactly why I’m writing this. I want to understand design patterns better, and the best way I learn is by sharing what I learn.
I aim to explore at least one new design pattern every day (or at the very least, every week). This blog will serve as a journal of that journey, and I hope it helps others who are starting out too.
💭 What Are Design Patterns?
Design patterns are common solutions to common problems in software design. They aren’t code recipes you copy-paste, but rather, reusable ideas and structures for solving software challenges in a clean, proven way.
They help you think better, design better, and communicate better as a developer.
🧠 Why Design Patterns Matter
🧩 Help you solve problems in structured, reusable ways
📚 Build a strong foundation in system design and architecture
🤝 Make team discussions easier using shared vocabulary
🚀 Improve your code quality, readability, and flexibility
📂 Categories of Design Patterns
✅ Official "Gang of Four" (GoF) Categories:
Creational Patterns – Handle object creation
Examples: Singleton, Factory, Builder, PrototypeStructural Patterns – Handle object composition
Examples: Adapter, Composite, Facade, DecoratorBehavioral Patterns – Handle object interaction
Examples: Observer, Strategy, Command, State
❗ Other Useful Categories (Not GoF):
Concurrency Patterns – Handle multi-threading and parallelism
Examples: Thread Pool, Producer-Consumer, Read-WriteArchitectural Patterns – Handle high-level system structure
Examples: MVC, Microservices, MVVM
📌 Join the Journey
I’m building a collection of easy-to-understand Java examples for each pattern I learn, and I’d love for you to follow along.

Star it, fork it, and grow with me as I explore one pattern at a time.
Let’s keep learning—one pattern, one problem, one post at a time.
