What is a Framework?
A framework is a pre-built structure or set of tools that provides a foundation for software development. It includes reusable components, libraries, and functionalities that help developers create applications more efficiently by providing a template to work on. Frameworks often offer a standardized way of doing things, guiding the overall design and implementation of an application in a particular programming environment.
Popular Java Frameworks
Let’s explore some of the most popular Java frameworks that are widely used by developers and tech giants:
1. Spring
Spring is a powerful and versatile open-source application framework for Java. It was created to address the complexities and challenges faced in enterprise application development. Spring’s primary aim is to simplify Java development by offering a comprehensive infrastructure and a wide set of tools.
