OOPs concept stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.
OOPs focuses on creating objects that contain both data and methods to manipulate that data.
Encapsulation, inheritance, polymorphism, and abstraction are the four main principles of OOPs.
Example: Inheritance allows a class to inherit properties and behavior from another class, promoting code reusability.
Constructors are special methods in a class that are used to initialize objects.
Constructors have the same name as the class they belong to.
They are called automatically when an object is created.
Constructors can have parameters to initialize object properties.
Example: public class Person { public Person(String name) { this.name = name; }}
