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.

Encapsulation, Inheritance, Polymorphism, and Abstraction are the four pillars of OOPs
Objects have state and behavior
Java supports interfaces, which allow for multiple inheritance

Java solves machine dependency by using bytecode and virtual machine.
Java code is compiled into bytecode which is platform-independent
The bytecode is executed by the Java Virtual Machine (JVM) which is platform-specific
JVM translates bytecode into machine code for the specific platform
This allows Java code to run on any platform with a JVM installed
Example: A Java program compiled on Windows can run on Linux or Mac as
