What is OOPS?
OOPS stands for Object Oriented Programming System. OOPS is the programming language based on the concepts of objects where data and code are present. Data is present in the form of fields and code is present in the form procedures.
Here are some of the core concepts of OOPS:
- Classes and Objects
- Class
- Object
- Inheritance
- Single Inheritance
- Multiple Inheritance
- Multilevel Inheritance
- Hierarchical Inheritance
- Hybrid Inheritance
- Encapsulation
- Access Modifiers
- Getters and Setters
- Polymorphism
- Compile-time Polymorphism (Method Overloading)
- Runtime Polymorphism (Method Overriding)
- Abstraction
- Abstract Classes
- Interfaces
Advantages of using OOPS
- Troubleshooting becomes easier with OOPS Language
- Productivity in the Coding
- Data Redundancy
- Code Flexibility
Object Oriented Programming (OOP) concepts are one the essential parts of modern programming and being a master is important for creating robust, scalable, and maintainable code. OOPS mcq questions help you to apply its concepts in practical scenarios. Regular practice with oops concept mcq sharpens individual problem-solving skills and helps them to clear their technical interview rounds as well.
