What are the usual responsibilities of a Java developer? You need to understand what you are going for and what, in the end, you will do, don’t you? I would like to talk about the main Java tasks that a developer should perform. These tasks can be quite difficult for you. But don’t worry, you can get Java programming help on special services. These services employ experts who are well versed in this language. They will help you with any task.
So what are the responsibilities of a Java developer?
- Development of new solutions
Developers always need to invent something. It could just be a Jira task that will be assigned to you, and you will work on developing a new solution. It can also be a discussion on a group call of the team: everyone will be able to express their opinion and propose the best approach. And here we would like to make a few points.
Firstly, being a developer is a very creative field, as you need to come up with unique ways to solve problems with standard tools. Often, one task can have many different solutions: everything depends on the creativeness of the developer, the accumulated knowledge base, and experience.
Secondly, the developer must be flexible in the sense that you should not be stuck in one solution and become closed to others. This can happen for various reasons: for example, you want to prove your viewpoint, or you have already developed and implemented your own solution, which you like very much and, of course, do not want to admit that it is not the best one.

- Writing new functionality
This is a logical step after the previous one – the implementation of new functionality. They divide all work on the project into tasks in the Jira, which the developers receive. There are various approaches to this issue – “methodologies.” As a rule, tasks have “Estimation” – the predicted time spent on execution. It is set either by you yourself when you take on a task, or by a team leader, or during planning, the developers jointly figure it out.
This time is very rarely guessed exactly since different factors affect the development. For example, such factors can affect: whether a programmer is familiar or not familiar with this technology, what is their general experience, various pitfalls that may become visible already during development, etc. Therefore, if you do not meet this time when developing the functionality, nothing bad will happen. These are just general guesses.
But again, not all projects have task estimation, and, as for me, it’s much easier to live without it, especially when a project manager doesn’t ask you a couple of times a day with the question, “Where are the estimates?”
Accordingly, you take the task, develop the necessary functionality, upload it to the general branch in GIT, and in the Jira, transfer the status of the task to “Ready for review,” and pray that it will not be returned to you with comments on revision.

- Writing tests for functionality
The person checking your code – the reviewer – liked the functionality you developed, but they have a question: where are the tests for it? And they return the task to you for revision. Tests are an important part of a Java app. By running them, you can immediately catch the places where the app does not work properly.
For example, a developer made some changes in one part, which led to changes in behavior in another and did not notice this during development. By running the tests, a developer will be able to see the failed (not working correctly) tests. This will tell them that something is broken in another part of the system. Therefore, they will not upload breaking changes to the server but will continue to refine their solution.
If you have problems with any of these tasks, get Java programming help. Always remember that any problem can be solved with a suitable helper!
