Is OOP better than procedural?
Procedural programming does not have any proper way for hiding data so it is less secure. Object oriented programming provides data hiding so it is more secure. … In procedural programming, function is more important than data. In object oriented programming, data is more important than function.
Why OOPs concept is used?
Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function. OOPs Concepts: Polymorphism.
Should I learn 2020 Java?
There are numerous reasons why Java continues to be a leader in the world of development and why it is still a language worth learning in 2020.
