Fredrick DooleyIn the field of software development, there are a huge number of professions with which a young professional can start his way. One of the best such options is definitely Java.
What does it mean to be a Java developer?
First, let’s talk about the basics. What is Java? Surely you understand that it is first of all a programming language, but it is also a platform for implementing digital projects. Java is multifunctional, compatible with almost all carriers and therefore suitable for creating all kinds of products: from mobile programs to complete servers, etc.
Java developers are IT specialists who have studied this language together with the platform of the same name and create software using it, edit existing software or give a second life to outdated projects.
This specialist is also responsible for the next stages of work on the software product. After the program is implemented it must be tested, corrected the identified errors and then tested again. If there is a need it must be russified and then implemented.
Java is suitable for writing servers, web sites, mobile applications, games and even for data engineering while working with Big Data.
Why Java?
For beginners, it really is one of the most suitable options:
- Because of the tool’s versatility, you can work in a variety of niches.
- Java is not difficult to master. First of all, because the language is very popular and there are a lot of tutorials, books, and courses available now.
- Even at the first level, Java developers can earn high salaries.
- According to CNews, Java programmers are among the top most in-demand IT professionals.
- Newcomers are also in demand, so you don’t have to fear the hassle of finding a job.
Classification of specialists
Programmers can be conditionally divided into 5 categories. The main criteria of classification are experience, knowledge, skills, portfolio content and agreement to expand their work front.
Junior. A novice developer, capable of making basic constructs, as well as doing testing. Juniors often operate under the guidance of a more experienced programmer.
Middle. The most filled niche are specialists of this level. They include an average developer who is able to write code for all the stages of software creation and launch it independently.
Senior. A true professional and expert in his craft, a person with a lot of experience, capable of taking full responsibility for the desired result during the task.
Tech Lead. This is a señor who has junior employees “in his charge”. He is in charge of the project in its entirety, shaping the technical tasks and then assigning them to the executing party.
Architect. Creates complex projects, including services and databases, is engaged in mentoring, has a lot of useful skills, is able to develop a project without the participation of junior staff.
As for the last 2 categories, their responsibilities are quite vague. The most in-demand are juniors and middles. But not every organization can afford to hire a junior.
Skills of Java developers
The work front of a Java programmer depends on the approach of employers and the ability of the specialist himself.
A junior must:
- Be proficient in Java;
- know the principles of OOP;
- work with frameworks;
- understand basic algorithms and basic structures.
Sometimes companies require a basic knowledge of other programming languages or auxiliary tools (for example, when a programmer is needed to develop Android applications).
Midle should:
- Work easily with OOP and MVC;
- form SQL queries (there are cases when this kind of requirement is also applied to juniors);
- Write easy to understand and concise code;
- be able to use the DRY (Don’t repeat yourself) and KISS (keep it simple, stupid) principles.
Senor must:
- be able to develop under Hybris, use different models;
- Analyze infrastructure, look for and fix bugs;
- Have the skills to create a software architecture;
- Be able to create servers and databases;
- plus all the things already mentioned above.
