#25 Association (HAS-A) vs Dependency (USES-A) vs Inheritance (IS-A) || Java Classes Relationship

🔍 In this video, you’ll learn the difference between HAS-A, USES-A, and IS-A relationships in Java. We’ll explore: ✅ Association (HAS-A) – When one class contains a reference to another ✅ Dependency (USES-A) – When one class uses another temporarily ✅ Inheritance (IS-A) – When one class inherits properties from another These object-oriented programming (OOPs) concepts are frequently asked in Java interviews and important for understanding class design in real-world projects. 📘 Topics Covered: What is Association in Java?
