OOPs concepts in Java simple Definition? OOPs (Object-Oriented Programming) in Java include Encapsulation (data hiding), Abstraction (hide details), Inheritance (reuse code), and Polymorphism (multiple forms). It improves code reusability, security, and maintainability.What is constructor in OOPs? A...

Classes –A class can be stated as the blueprint of the object. This states what an object can do. It contains all the features, attributes, and behavior of what the model can do. We can say that class contains the definition of the object.Example –Car color, engine type, etc. And...

user creates objects from thenew()class and invokes the price() method, the definitions for the price method inside thenew()class comes into play. These definitions are hidden from the user. The Abstract method is just providing a declaration. The child classes need to provide the definition....

Jay - I am facing difficulty in understanding the OOPS concepts. I know the basic definition but don't know how it adds value to writing a good code. Jane - Okay! No worries let's start with Inheritance. You know from biology that a child inherits physical properties from parents or anc...
