Java Frameworks are pre-written codes that you can add to your written code to solve a specific problem. These are similar to programming languages such as C++ but more simplified and advanced. Developers can make use of any of these frameworks by calling its inheritance, methods, supplying the callbacks, the listeners, and any other pattern implementation. Frameworks also dictate an application’s structure; some even provide sufficient code that you do not need to do the added heavy lifting on your application.
