Top Infosys Interview Questions and Answers

  1. Can you explain the four basic principles of OOPs?

Answer: The four basic principles of OOPs are as follows

  • Data Encapsulation- This basically occurs when data and its corresponding code are combined into a single unit, referred to as a class.
  • Abstraction- This refers to the representation of vital properties without their background framework. 
  • Inheritance- This refers to the transfer of an already existing property to a new class. The existing class is then called the parent class, and the new class is referred to as the child class. 
  • Polymorphism- As the name suggests, polymorphism is an ability of an object to take on varied forms. It enables cross-movement between the child class and the parent class. 
  1. What do you understand by an object in OOPs?

Answer: An object in OOPs is the subset of a class with individual properties and attributes. Take the example of a bouquet of flowers. Each flower has its unique properties, such as varied shapes, scents, and colors. All these are known as a collection of objects. 

  1. What do you understand by a class in OOPs?

Answer: A class is basically an instance of an object that determines its behavior and what it will include. One of the most important points of difference between class and object is that a class can exist without an object; however, you can never find an object without a class. 

  1. How can you differentiate between method overloading and method overriding?

Answer: Method overloading refers to finding two or more methods with the same name but with a different number of parameters. It is also often referred to as compile-time polymorphism because it happens during the compile time.  

Method overriding, also known as runtime polymorphism, happens when the program is executed. It refers to the process through which you can construct sub-class and super-class methods, with the sub-class taking precedence over the super-class. One important thing to note is that, in this case, both the sub-class and super-class methods have identical signatures and names. 

  1. What are access specifiers? What are the different types of access specifiers?

Answer: Access specifiers are responsible for defining how members can be accessed. Typically, there are three kinds of access specifiers, namely, private, public, and protected. 

Private- As quite understandable from the same itself, private members cannot be accessed by anyone outside of the class.

Public- Contrary to private access specifiers, members defined as public can be easily accessed from anywhere.  

Protected- Under this type, you can only access the members from outside the class if they are members of a child class.

  1. Can you state some limitations of OOPS?

Answer: Although object-oriented programming allows users to enjoy a series of benefits, there are also certain limitations. Some might include:

  • Compared to other programs, OOPS can be quite prominent in terms of size. 
  • OOPs, have also been known to operate much slower than most other programs and are quite labor-extensive to create.
  • Certain improvisations and adjustments are required in OOPs to enjoy their full benefits. 
  1. Why do we need OOPs?

Answer: There are innumerable benefits that you can derive from implementing OOPs. Some of them might include,

  • You can easily upgrade OOPs systems from large to small systems. 
  • With the help of OOPs, you no longer need to write code from scratch since you can easily build programs from standard working modules. This, in turn, helps to reduce the consumption of a lot of time and energy, both of which are vital for any organization. 
  • OOPs also help to target one single problem at a time by breaking down the program into small parts. 
  • OOPs, enable users to extend the use of existing classes.
