Chain of Responsibility Design Pattern Java 🔗 | Explained with Real Examples

The Chain of Responsibility Design Pattern in Java is a powerful behavioral pattern that helps you decouple the sender of a request from its receiver. Instead of hardcoding a single handler, you can pass the request through a chain of handlers until one processes it. 🎯 In this video, you’ll learn: ✅ What is the Chain of Responsibility Pattern in Java ✅ Real-world use cases: 1) Interview process approvals 2) Code/documentation reviews 3) Logging systems ✅ Types of chains: 1) Chain Breaker (first one to handle it) 2) Exactly One Handler 3) All Handlers (broadcast-style) ✅ When to use it: 1) You need a chain of processing steps, each responsible for a small part 2) You want to decouple the client from the exact handler implementation ✅ UML diagram to visualize the pattern ✅ Java code example with clean, modular structure 📚 Based on: https://nailyourinterview.org/intervi...
