Runtime polymorphism is the ability of a function to behave differently based on the object it is called with.
Runtime polymorphism is achieved through method overriding in object-oriented programming.
It allows a subclass to provide a specific implementation of a method that is already provided by its superclass.
The actual method that gets called is determined at runtime based on the type of object.
Example: Inheritance ...
Abstraction is the concept of hiding complex implementation details and showing only the necessary information to the user.
Abstraction allows developers to focus on the essential features of an object while hiding unnecessary details.
It helps in reducing complexity and improving the efficiency of the code.
For example, a car can be abstracted as a vehicle with properties like speed, fuel consumption, and color, without ...
Code to find duplicates in an array of strings
Iterate through the array and store each element in a HashSet

Hashing is a process of converting input data into a fixed-size string of bytes using a hash function.
Hashing is used to securely store passwords by converting them into a hash value.
Hashing is used in data retrieval systems to quickly locate data based on a key.
Common hash functions include MD5, SHA-1, and SHA-256.

A class is a blueprint for creating objects in object-oriented programming.
Defines the properties and behaviors of objects
Can be used to create multiple instances of objects
Encapsulates data and methods within a single unit
An object is a self-contained entity that consists of data and methods to manipulate that data.
Objects are instances of classes in object-oriented programming.
They have attributes (data) and methods (functions) to operate on the data.
Objects can interact with each other through method calls.
Example: In a car simulation program, a 'Car' object may have attributes like 'color' and 'speed', and methods like 'accelerate' a
The login page is displayed when a user clicks on a webpage icon like Facebook by redirecting to a separate login page.
Clicking on the webpage icon triggers a redirect to the login page
The login page prompts the user to enter their credentials
After successful login, the user is redirected back to the original webpage
Object-oriented programming in Java involves creating classes, objects, inheritance, polymorphism, and encapsulation.
Classes are blueprints for objects, defining attributes and behaviors.
Objects are instances of classes, representing real-world entities.
Inheritance allows a class to inherit attributes and methods from another class.
Polymorphism enables objects to be treated as instances of their parent class.
Encapsulat...
