|Java - Interview Questions and Answers|
|Ans. Encapsulation facilitate hiding and restricted access and hence more of a security feature. Encapsulation is definitely a great feature as when applications expand criss cross communication between objects / modules could lead to blunders.|
Inheritance facilitates code reuse.
Polymorphism comprise of method overloaded ( which to me is negligible usage ) and method overriding. Method overriding is of great usage as it facilitates concept of interfaces and plugin development.
So it’s Security / Organization vs
Code Reuse / Support for other features like overriding vs
Contracts / Plugin Development facilitating the creation of frameworks / libraries.
Which is more important may vary from application to application , its scale , its use , its sensitivity etc.
