What is Spring and its Importance? 

Spring is a powerful framework for building Java applications. It is significant as it offers a comprehensive programming and configuration model that supports enterprise-level development. Developers use Spring to manage application components through dependency injection, which creates modular and testable code. 

Spring Boot, an extension of the framework, simplifies project setup and accelerates application deployment through preconfigured defaults. Its architecture encourages layered design which improves maintainability over time.
