Top OOPS Interview Questions and Answers for Experienced Professionals

Knowing answers to commonly ask OOPS interview questions for feel professionals is important to ace technical interviews. In this part, we ’ ll attend at some commonly-asked OOPS interview questions and answers for experienced professionals .

Q1. What are the biggest benefits/advantages of using Object-Oriented Programming?

This is one of the most common OOPS interview questions for feel developers. Some noteworthy benefits of using Object-Oriented Programming include :

  • OOP allows code to be reused through its feature of inheritance, thereby eliminating code redundancies. 
  • The OOP model offers complete clarity in programming expression, thereby allowing developers to perform complex programming tasks with simplicity.
  • OOP has the feature of data binding, thereby allowing data and information to be kept confidential and private.
  • OOP allows data and the code to be bound together through encapsulation, reducing the burden on developers.
  • Polymorphism allows code entities to take multiple forms, allowing developers to perform multiple programming tasks simultaneously.

Q2. What do you understand by Polymorphism in Object-Oriented Programming?

polymorphism is a sport in OOPs where functions, objects, and variables can take multiple forms. This means that classes can have methods and functions of the like name but perform different functions at a given point. There are two types of Polymorphism – static Polymorphism and Dynamic Polymorphism .

Q3. What is Inheritance in Object-Oriented Programming?

inheritance is a core Object-Oriented Programming sport where classes can inherit the properties of early classes. This helps developers form associations while coding, helping them eliminate redundancy in code or code blocks .

Q4. What do you understand by Method Overloading in Object-Oriented Programming?

This is one of the most democratic OOPS interview questions for experience programmers. Method Overloading is a feature of speech that allows methods to be defined by the same name, but perform unlike functions within the lapp classify, if the arguments passed are different .

Q5.  What is Data Abstraction in Object-Oriented Programming?

Data Abstraction is another core feature in OOPs that allows developers to display entirely the relevant information to the exploiter and hide the implementation details. Data ABstraction enables data and information to be observe secret and confidential, thereby ensuring the security of the program/application.
