I appeared for an interview before Mar 2023.
Object-oriented programming paradigm focusing on objects and classes.
Encapsulation: Bundling data and methods that operate on the data into a single unit (object)
Inheritance: Ability of a class to inherit properties and behavior from another class
Polymorphism: Ability to present the same interface for different data types
Abstraction: Hiding the complex implementation details and showing only the necessary features
I applied via Company Website and was interviewed in Mar 2022. There were 3 interview rounds.
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are of the same class.
It is achieved through method overriding and method overloading.
Example: A parent class Animal can have child classes like Dog, Cat, and Cow. All these child classes can have their own implementation of the method 'makeSound', which is overridden from the parent ...
Java interface is a blueprint of a class that has only abstract methods and constants.
An interface is declared using the interface keyword
It cannot be instantiated directly
It can be implemented by a class using the implements keyword
All methods in an interface are public and abstract by default
Interfaces can also have static and default methods
Example: public interface Drawable { void draw(); }

I applied via Campus Placement and was interviewed in Aug 2020. There were 5 interview rounds.
Real-time implementation of OOPs concept involves creating objects and classes that interact with each other in real-time applications.
Real-time systems require objects to be created and destroyed dynamically
Inheritance and polymorphism can be used to create flexible and extensible systems
Real-time systems often use event-driven programming to respond to user input
Examples include video games, financial trading systems

OOPS is a programming paradigm based on objects that have properties and methods.
Encapsulation: bundling of data and methods that operate on that data within a single unit
Inheritance: ability of a class to inherit properties and methods from a parent class
Polymorphism: ability of objects to take on many forms or have multiple behaviors
Abstraction: hiding of complex implementation details and showing only the necessary ...
Explanation of Super, Throw, Final and Finally
Super: used to call a method from a parent class
Throw: used to throw an exception
Final: used to declare a constant or to prevent method overriding
Finally: used to execute code after try-catch block, regardless of exception
