How to create a Java framework in 5 minutes?

Knowing the difference between a library and a framework, we can safely start creating our own small framework.

What is the purpose of creating a framework?

The goal is to define the boundaries and manage the process of the program. Clear boundaries and requirements give an understanding of where developers implement the necessary functions and how to integrate with the framework.

Writing a simple framework in Java

In the example below, we will implement the framework and set the framework in which the developer will work:

The following is the class. Developers can extend it with their features:

Now let's write the so-called "Template", which is the idea of the framework - how it should function:

That's it! This small framework allows, or rather obliges, developers to inherit the . In it, developers can only override the method , for example, like this:Move.javaaction()

And this will all work in the Main class with the main method main(). It is an entry point and cannot be changed.

In this article, we wrote the simplest implementation of the framework. The structure of real frameworks is very complex: it includes multiple dependencies and relationships that line up in a complex process, allowing you to maximize performance and focus on implementing the business logic of the application.
