Frameworks are essential to the creation of software because they offer pre-made structures and libraries that help programmers create reliable, scalable, and effective programs. These frameworks provide a base for developers to build on, easing the process and letting them concentrate on application-specific logic rather than having to create it from scratch.

What is a Framework in Java? 

You might be wondering what is a framework in Java with example, right? Here it is! A framework in Java is a pre-written, reusable codebase that offers a structured environment for creating applications. It comprises a selection of tools, conventions, and libraries that make it easier for programmers to create software. Java frameworks for web development include built-in components and procedures that may be used to handle frequent activities like managing sessions, interacting with databases, and processing requests. Developers may hasten the development process, lessen code duplication, and guarantee better code structure by using frameworks.v

What is a Framework?
