Q2. Tell me about abstraction and interfaces
Ans. 
Abstraction is the concept of hiding complex implementation details and showing only the necessary features. Interfaces define a contract for classes to implement.
• Abstraction allows us to focus on what an object does rather than how it does it

• Interfaces define a set of methods that a class must implement, without specifying how they are implemented

• Abstraction and interfaces help in achieving loose coupling and flexibil...read more

Q3. Array lists vs arrays
Ans. 
Array lists are dynamic in size, while arrays have fixed sizes.
• Array lists can grow or shrink in size dynamically, while arrays have a fixed size.

• Array lists are implemented using dynamic arrays, while arrays are static data structures.

• Array lists provide methods for adding, removing, and accessing elements easily, while arrays require manual resizing and shifting of elements.

• Example: ArrayList<String> vs String[

Q1. Why OOPs is used
Ans. 
OOP is used for organizing code into reusable objects, promoting code reusability, modularity, and easier maintenance.
• Encapsulation: Data and methods are bundled together in objects, promoting data security and code organization.

• Inheritance: Allows for the creation of new classes based on existing ones, promoting code reuse and reducing redundancy.

• Polymorphism: Objects can be treated as instances of their parent class,...read more

Q2. What is multiple inheritance
Ans. 
Multiple inheritance is a feature in object-oriented programming where a class can inherit attributes and methods from more than one parent class.

• Can lead to the diamond problem where ambiguity arises if two parent classes have a method with the same name

• Languages like C++ support multiple inheritance

Q3. What is mentioned bypolymorphism
Ans. 
Polymorphism is the ability of a single function or method to operate on different types of data.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

• Example: A method 'draw()' ca...read more
