Como o Java é Utilizado no Back-End?

Java é uma linguagem de programação bastante versátil. Ela pode ser usada para escrever uma ampla gama de programas, desde aplicações web até jogos eletrônicos completos. Vamos tomar como exemplo uma aplicação web, ou simplesmente um site, e explorar a função do Java:

How does a web application work?

To begin with, it's important to understand how a web application functions in general. It's quite straightforward. When you click, for instance, the registration button on a website, the frontend sends this data and a request for assistance to the backend. The backend recognizes that it has a task from the frontend, performs necessary operations, such as saving the user to the database and registering them, and then sends back information to the frontend, indicating that everything went well.

In this way, the backend and frontend work together. In this symbiotic relationship, Java plays the role of the backend. Java will receive data and requests from the frontend and carry out the application's work that the user doesn't see.

I think you can see that there's nothing too complicated here. But what exactly does Java do? Java performs various logical operations, processes information, retrieves data from the database and writes it there, and works with various third-party APIs to process and transmit information to the frontend.

Eu acredito que você pode perceber que não há nada muito complicado aqui. Mas o que exatamente o Java faz? O Java realiza diversas operações lógicas, processa informações, recupera dados do banco de dados e os escreve lá, e trabalha com diversas APIs de terceiros para processar e transmitir informações para o front-end.
