  • Q2. Explain oops concepts?
  • Ans. 

    OOPs concepts are the principles of Object-Oriented Programming that help in designing and implementing software solutions.

    • Encapsulation - binding data and functions together

    • Inheritance - creating new classes from existing ones

    • Polymorphism - ability of objects to take on multiple forms

    • Abstraction - hiding implementation details

    • Objects - instances of classes that encapsulate data and behavior

  • Answered by AI
  • Q3. What is inheritance and disadavantages of it?
  • Ans. 

    Inheritance is a mechanism in OOP where a new class is derived from an existing class.

    • It allows for code reusability and promotes a hierarchical structure.

    • It can lead to tight coupling and make the code harder to maintain.

    • It can also result in the creation of unnecessary classes and increase complexity.

    • Example: A Car class can inherit properties and methods from a Vehicle class.

    • Example: A Square class can inherit prope

  • Q4. Explicite interface?
  • Ans. 

    Explicit interface is a way to implement multiple interfaces with same method names.

    • Explicit interface is used to avoid naming conflicts when implementing multiple interfaces.

    • It is implemented by prefixing the interface name to the method name.

    • It is useful when implementing COM interfaces in .NET.

    • Example: void IInterface1.Method() and void IInterface2.Method()

  • Answered by AI
  • Q5. Interface vs abstract classes
  • Ans. 

    Interface defines only method signatures while abstract class can have method implementations.

    • Interfaces can be implemented by multiple classes while abstract classes can only be extended by one class.

    • Interfaces are used for achieving multiple inheritance in Java while abstract classes are used for single inheritance.

    • Interfaces cannot have constructors while abstract classes can have constructors.
