Polymorphism allows methods to do different things based on the object that it is acting upon, enhancing flexibility in code.

Example of method overloading: multiple methods with the same name but different parameters.
Example ...
Java is a high-level, object-oriented programming language designed for portability, performance, and ease of use.
Platform-independent: Write once, run anywhere (WORA) - Java code can run on any device with a Java Virtual Machine (JVM).
Object-oriented: Supports concepts like inheritance, encapsulation, and polymorphism, making code reusable and modular.
Rich API: Provides a vast set of libraries and frameworks, suc...
OOP in Java is a programming paradigm based on objects, emphasizing encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: A class 'Car' with attributes like 'speed' and methods like 'accelerate()'.
Inheritance: Mechanism where one class inherits properties and behavior from another. Example: 'Sedan' class inherit...
Hashing is a process that transforms input data into a fixed-size string of characters, typically for data integrity and security.
Hash functions take an input (or 'message') and return a fixed-size string of bytes.
Common hashing algorithms include MD5, SHA-1, and SHA-256.
Hashing is used in password storage to securely store user credentials.
A hash is deterministic; the same input will always produce the same outpu...
