Polymorphism allows methods to do different things based on the object type, enhancing flexibility in programming.
Polymorphism is a core concept in Object-Oriented Programming (OOP).
It allows methods to be defined in multiple forms.
There are two types: compile-time (method overloading) and runtime (method overriding).
Example of method overloading: a function 'add' can add integers or doubles.
Example of method over...
OOP concepts include encapsulation, inheritance, polymorphism, and abstraction, forming the foundation of object-oriented programming.
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 a new class derives properties and behavior from an existing class. Example: 'E...
SQL Joins combine rows from two or more tables based on related columns, enabling complex queries and data retrieval.
INNER JOIN: Returns records with matching values in both tables. Example: SELECT * FROM A INNER JOIN B ON A.id = B.id;

An immutable class is a class whose instances cannot be modified after creation, ensuring data integrity and thread safety.
Immutable classes prevent changes to their state after creation, e.g., String in Java.
They often provide methods to return new instances with modified values, e.g., LocalDate in Java.
Immutable objects are inherently thread-safe, reducing synchronization issues.
Commonly used in functional progr...

Interfaces define contracts for classes, while abstract classes provide a base with shared code and can have implemented methods.
An interface can only declare methods, while an abstract class can declare methods and provide some implementation.
A class can implement multiple interfaces but can inherit from only one abstract class.
Interfaces are used for defining capabilities (e.g., Comparable), while abstract class...
