How is Java used in the Backend?

Java is a fairly versatile programming language. It can be used to write a wide range of programs, from web applications to full-fledged video games. Let's take a web application, or simply a website, as an example, and explore Java's role:

How does a web application work?

To start, it's essential to understand how a web application typically works. It's pretty simple. For example, when you click the registration button on a website, the frontend sends the data and a request to the Backend for processing. The Backend receives this request, handles the necessary operations—like saving the user to the database and registering them—and then sends a response back to the frontend confirming that everything was successful.

This is how the Backend and frontend collaborate. In this partnership, Java takes on the role of the Backend, handling data and requests from the frontend and performing the behind-the-scenes tasks that users don't directly see.

I'm sure you can see that there's nothing too complex here. But what exactly does Java do? Java handles various logical operations, processes data, retrieves and stores information in the database, and works with third-party APIs to manage and send data to the frontend.
