Q. Explain different OOPS concepts?
Ans.
Polymorphism
Ability to take more than one form, in java we achieve this using Method Overloading (compile time polymorphism), Method overriding (runtime polymorphism)
Inheritance
Is the process by which one object acquires the properties of another object. The advantages of inheritance are reusability of code and accessibility of variables and methods of the super class by subclasses.
Encapsulation
Wrapping of data and function into a single unit called encapsulation. Ex:- all java programs.
(Or)
Nothing but data hiding, like the variables declared under private of a particular class are accessed only in that class and cannot access in any other the class. Or Hiding the information from others is called as Encapsulation. Or Encapsulation is the mechanism that binds together code and data it manipulates and keeps both safe from outside interference and misuse.
Abstraction
Nothing but representing the essential futures without including background details.
Dynamic binding
Code associated with a given procedural call is not known until the time of the call at runtime. Dynamic binding is nothing but late binding.
