Inheritance & Composition in Java

In object-oriented programming (OOP), inheritance and composition are two primary mechanisms for building complex systems. Inheritance allows a class to inherit properties and methods from another class (the parent or base class), while composition involves creating a class that contains instances of other classes as its components. Inheritance represents an "is-a" relationship, where a subclass is a specialized version of a base class. Composition, on the other hand, models a "has-a" relationship, where a class contains or uses other objects.
