🚀 Day 18 of My Automation Journey – Inheritance QA's

In today’s session, I explored one of the core pillars of Object-Oriented Programming (OOP) — Inheritance. Inheritance allows a class to reuse properties and methods from another class, which helps reduce code duplication and improve maintainability. Today I practiced: Basic inheritance concepts Types of inheritance Real-world coding scenarios Tricky inheritance interview questions Let’s go step by step. 🔹 1. What is Inheritance? Inheritance is a mechanism in Java where one class acquires the properties and behaviors of another class. The class that is inherited from is called the Parent Class (Superclass) and the class that inherits is called the Child Class (Subclass). Example: class Parent { } class Child extends Parent { } Here: Parent → Superclass Child → Subclass 🔹 2. Why is Inheritance Used? Inheritance is mainly used for code reusability. Benefits include: ✔ Reusing existing code ✔ Reducing duplication ✔ Improving maintainability ✔ Supporting polymorphism ✔ Creating hierarchica
