APIs can be categorized into different types such as REST, SOAP, GraphQL, and RPC.
RESTful APIs: Representational State Transfer APIs use standard HTTP methods like GET, POST, PUT, DELETE for communication.
SOAP APIs: Simple Object Access Protocol APIs use XML for message exchange over a network.
GraphQL APIs: Query language for APIs that allows clients to request only the data they need.
RPC APIs: Remote Procedure Call AP...
Different types of testing include functional testing, non-functional testing, manual testing, automated testing, regression testing, and performance testing.
Functional testing: Testing the functionality of the software against the requirements.
Non-functional testing: Testing aspects like performance, usability, and security.
Manual testing: Testing performed manually by testers.
Automated testing: Testing performed usin...

Oops Concepts are fundamental principles of object-oriented programming such as Inheritance, Encapsulation, Polymorphism, and Abstraction.
Inheritance: Allows a class to inherit properties and behavior from another class.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Polymorphism: Ability of a function to behave differently based on the object it is acting upon.
Abstraction: Hiding t...
