If you have just started learning Java or are still thinking about which programming language to learn, this text is for you. It is much easier to find motivation when you know the end goal. In the vast world of IT, it is easy to get confused - a sea of specializations and positions can drive you into a stupor. To prevent this from happening, we talk about the four most popular areas in development and tell you what technologies you need to master. We hope this will help you choose your own development path.
Backend developer
A backend developer deals with that part of the application / site / software that is “under the hood”. And this is a lot of different tasks. The essence of the work of such a developer is to create a working combination of "server-application-database" by writing code that runs on a server - physical or cloud. The backend developer is responsible for the logic, proper functioning and good performance of the application.Technology stack

- Resource architecture design.
- Formation of the structure of the website.
- Building the platform and core feature set.
- Writing algorithms.
Salary
The average salary of a backend specialist, according to the Dou website , in Ukraine is about $2,380. June receives from 850 dollars, and the signor - about 4 thousand dollars. But in Russia, according to the Habr survey , the average salary of a backend developer is lower, about $1,900.Frontend developer
A front-end developer is a programmer responsible for the visual part of a website, application, or software. Do not confuse it with a coder, because the functionality of a frontend developer is much wider. It not only typesets, but also “revives” the made-up image due to pop-up windows, adjusts the work of buttons and interacts with the server part of the application. To work as a frontend developer, you need to master languages such as HTML, CSS, JavaScript. Knowledge of Java will provide the necessary foundation for understanding object-oriented programming. In the future, a person who has the skills of a frontend developer can retrain as a backend developer, and later on as a fullstack developer. So there is room for improvement.Technology stack

Salary
According to a Dou survey , front-end developers in Ukraine make about $2,300 on average. Junes can earn from 750 dollars, and seniors about 4 thousand dollars. In Russia, according to a survey by Habr , on average, frontend girls receive about $1,630.Full stack developer
A fullstack developer is a human Swiss knife in the development world, a multifunctional programmer who can handle both frontend and backend tasks. It is not easy to become such a universal soldier: one must have extensive knowledge and rich experience. Naturally, a fullstack developer can become a specialist who managed to work both on the visual part of the application and on the server side. In addition, he must have a good idea of how these parts interact and what the final project should be like.Technology stack
- Java + Java Core; apache; JPA/Hibernate Spring (Spring MVC, Spring Boot, Spring REST, Spring Web), Google Cloud, AWS, or Azure JSP (Java Server Pages).
