Inheritance promotes code reusability by letting a child class inherit properties and behaviors from a parent class. Java supports single and multilevel inheritance but bars multiple inheritance through classes to prevent the "Diamond Problem." Polymorphism

Object-Oriented Programming is the heart of Java, and Durga Sir's notes present these concepts with the perfect mix of theory and practical implementation.
: Utilizes wait() , notify() , and notifyAll() methods from the Object class to let threads coordinate states safely, preventing race conditions. 7. Java Collection Framework The programmer must explicitly handle or declare them
This extensive section covers far more than just the four pillars of OOPs, delving into practical implementation aspects and interview-focused nuances. It is the most critical part of the Core Java syllabus.
Inheritance allows a new class (child/subclass) to acquire the properties and behaviors of an existing class (parent/superclass).
