30. Introduction to Frameworks (e.g., Spring Basics)
Frameworks play a crucial role in modern application development by promoting best practices, enhancing productivity, and ensuring maintainability. Spring Framework is one of the most prominent frameworks in the Java ecosystem due to its modularity, flexibility, and extensive adoption in enterprise applications. It leverages principles such as Inversion of Control and Dependency Injection to facilitate the creation of clean and scalable software solutions, while Spring Boot simplifies the setup process for new applications.

- Spring Framework offers a comprehensive infrastructure support for Java applications.
- Key concepts of Spring include Inversion of Control, Dependency Injection, and Spring MVC architecture.
Key Concepts
- -- Framework
- A reusable set of libraries or classes for a software system that provides functionality that can be extended by user code.
- -- Inversion of Control (IoC)
- A design principle where the framework controls the flow of the program instead of the developer.
- -- Dependency Injection (DI)
- A type of IoC where dependencies are provided to a class from an external source rather than created within the class.
- -- Spring Boot
- A tool that simplifies the setup and development of new Spring applications by eliminating boilerplate configurations.
- -- Spring MVC
- A web framework built on the Servlet API following the Model-View-Controller architecture.
