What is data abstraction in Oops?
Data abstraction is the simplest form of abstraction. When working with OOPS, you primarily work on manipulating and dealing with complex objects. This object represents some data but the underlying characteristics or structure of that data is actually hidden from you. Let’s go back to our example of making coffee.
Should a subclass override all abstract methods of an abstract class?
A subclass must override all abstract methods of an abstract class. However, if the subclass is declared abstract, it's not mandatory to override abstract methods. We can access the static attributes and methods of an abstract class using the reference of the abstract class.
