Behavioral Design Patterns: In-Depth Overview

Behavioral design patterns focus on communication and interaction between objects. They define how objects collaborate and delegate responsibilities, making systems more flexible and easier to maintain. Key Behavioral Design Patterns with Examples 1. Chain of Responsibility Passes requests along a chain of handlers until one of them handles it. Steps to Implement Java Example Spring Example Real-World Use Case Advantages Disadvantages 2. Command Encapsulates a request as an object, allowing…

Structural Design Patterns: In-Depth Overview

Structural design patterns deal with object composition and relationships, making it easier to build flexible and scalable systems. They focus on how objects and classes can be combined to form larger structures while ensuring that these structures remain efficient and maintainable. Key Structural Design Patterns with Examples 1. Adapter Pattern Acts as a bridge between incompatible interfaces by converting one interface into another that a client expects. 🎯 Goal: Allow…

Creational Design Patterns: In-Depth Overview

Creational design patterns are focused on the process of object creation, ensuring that the system remains flexible and reusable. These patterns abstract the instantiation process, allowing the creation logic to be separated from the usage of objects. Here’s a detailed guide with step-by-step examples in Java and applications in Spring Framework. Key Creational Design Patterns with Examples 1. Singleton Pattern Ensures a class has only one instance and provides a…

SOLID Principles with Before/After Examples

SOLID is a set of five design principles to make software maintainable, scalable, flexible, and testable. S — Single Responsibility Principle (SRP) A class should have only one reason to change. ❌ Before (Violation) Problem: The class handles both banking operations and logging. ✅ After (SRP Applied) Now: One class handles account operations, another handles logging. 💼 Banking Example Use Case Each has a single job. O — Open/Closed Principle…
