  • Inheritance: Mechanism to create a new class based on an existing class, inheriting its properties (e.g., a 'Dog' class inheriting from an 'Animal' class).

  • Polymorphism: Ability to present the same...

Q. What is an interface?
Ans. 

An interface defines a contract for classes, specifying methods and properties without implementing them.

  • An interface can contain method signatures and properties but no implementation.

  • Classes that implement an interface must provide concrete implementations for all its members.

  • Interfaces support multiple inheritance, allowing a class to implement multiple interfaces.

  • Example: In Java, 'Runnable' is an interface th...

  • Q1. Introduce yourself
  • Q2. Explain what is oops
  • Ans. 

    OOPs stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects.

    • OOPs focuses on creating objects that contain data and methods to manipulate that data.

    • It involves concepts like inheritance, encapsulation, polymorphism, and abstraction.

    • Example: Inheritance allows a class to inherit properties and methods from another class, promoting code reusability.

  • Answered by AI
  • Q3. What is inheritance
  • Ans. 

    Inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class.

    • Allows a class to reuse code from another class

    • Derived class inherits members from base class

    • Example: Class Car can inherit properties and methods from class Vehicle

  • Answered by AI
  • Q4. Explain different types of inheritance
  • Ans. 

    Types of inheritance in .NET include single, multiple, multilevel, hierarchical, and hybrid inheritance.

    • Single inheritance: A class can inherit from only one base class.

    • Multiple inheritance: A class can inherit from multiple base classes (not supported in C#).

    • Multilevel inheritance: A class can inherit from a derived class, creating a hierarchy of classes.

    • Hierarchical inheritance: Multiple classes can inherit from a si...
