🚀 Day 10 of My Automation Journey – Tricky Constructor Questions (Inheritance in Java)

Discussing tricky scenarios, let’s break this clearly and powerfully 💪 ✅ 1️⃣ Golden Rule of Constructors in Inheritance When a child object is created: 👉 Parent constructor executes first 👉 Then Child constructor executes Because every child class constructor implicitly or explicitly calls super() . 🎯 Scenario 1: Parent has NO-ARG constructor class Parent { Parent() { System.out.println("Parent No-Arg Constructor"); } } class Child extends Parent { Child() { System.out.println("Child No-Arg Constructor"); } public static void main(String[] args) { new Child(); } } 🔹 Output: Parent No-Arg Constructor Child No-Arg Constructor ✔ Java automatically inserts super(); 🎯 Scenario 2: Parent has ONLY Parameterized Constructor class Parent { Parent(int x) { System.out.println("Parent Parameterized Constructor"); } } class Child extends Parent { Child() { System.out.println("Child Constructor"); } } ❌ Compile Time Error! Why? Because Java tries to insert: super(); // default But Parent does NOT ha
