Question
What are the core concepts of OOPS?
Select one or more:
- Polymorphism
- Composition
- Cohesion
- Coupling
- Abstraction
Solution
The core concepts of Object-Oriented Programming (OOPS) are:
-
Polymorphism: This is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object.
-
Abstraction: It is a process of hiding the implementation details and showing only the functionality to the users. Abstraction lets you focus on what the object does instead of how it does it.
-
Composition: It is a design technique in object-oriented programming to implement has-a relationship between objects. Composition in java is achieved by using instance variables of other objects.
-
Cohesion: It is a measure of how closely the responsibilities of a module or a class are related to each other. The goal is to have high cohesion, i.e., a class or a module should have one and only one responsibility.
-
Coupling: It is a measure of how much one module or a class depends on the other modules or classes. The goal is to have low coupling, i.e., a change in one module or a class should not affect other modules or classes.
So, all the options you provided are core concepts of OOPS.
