In this session, we discuss one of the most commonly misunderstood concepts in Java:
👉 Is there inheritance when you write just class A {}?

🔍 Topics Covered:
What is java.lang.Object class?

Why is it called the root class in Java?

How every class in Java (user-defined or predefined) implicitly inherits from Object class

What is default inheritance in Java?

Role of the Java compiler in adding extends Object

How to verify inheritance using the javap tool

💡 Key Concept:
Even if you don’t explicitly use extends, Java automatically makes your class inherit from java.lang.Object.

🧪 Example Used:
java
class A { }

➡️ After compilation:
java
class A extends java.lang.Object { }

Yes! Arrays and even primitive wrapper classes derive from Object.
