It’s essential to highlight some must-have skills required for Java Juniors and explain what they do. So, what are the main duties of Java devs, and what should they learn first and foremost?
Basically, the primary responsibilities of Java Juniors include:
Development. Needless to say, the development process is one of the main duties of Java specialists — they should be able to write the code and build apps or websites as per the customer's requirements.
Testing. When the project is completed, Java specialists need to test it and fix the errors that occurred during the process. In other words, you should be able to make sure that each feature works smoothly.
System optimization. Be ready that most Java Juniors should be responsible for maintaining active systems, enhancing them, and providing software updates.
Collaboration with other departments. Most likely, you’ll work in a large team and collaborate with your co-workers as well as clients to create integrated software systems. That’s why good communication skills (both written and verbal) can set you above the rest of the candidates when applying for the job.
All that just being said, to get your foot in the door as a Java specialist, you need to have a set of essential skills. So what does Java Developer Kit

How to Grow from Junior to Senior
Be ready that after you start in a junior programming spot, you’ll remain there for about four years. As already mentioned, the main duties will include coding, debugging, reviewing code, and some technical documentation. All these duties and some more, you can find in our article What It’s Like to be a Junior Developer. A Short Guide
You should also be ready to go beyond writing code. It’s a pretty common mistake when fresh Java developers ignore everything else but jump to code only. Actually, writing a code is just a part of the bigger process and there are lots of other parts that are quite important, too. If you want to move ahead and don’t get stuck at your Junior positions for long years, you need to participate in architecting and designing as well. After a while, you’ll need to match the technical solutions to business needs, too. Flexibility
is one of the best attributes of expert developers.
Also, try to observe and learn once you have landed your first job. Don’t be afraid to ask questions to suck as much information as possible. It’s also a good idea to observe how your team members interact with each other, regardless of whether they are Junior devs like you or Senior devs that may mentor you. And, again, never stop learning
— get familiar with an IDE, try to write more maintainable and clean code, find out how version-control software works, etc. By following these tips, you’ll grow into a Middle Java specialist as quickly as possible. And at that spot, you may be interested in What It’s Like to be a Mid-Level Developer. A Short Guide to the Role
In brief, it’s not all about code. Of course, there’s nothing wrong with working on standard tasks, fixing bugs, and contributing to the codebases as a Middle dev. But after a few years in software engineering, you will also be able to understand all the workflows and processes. Additionally, you are likely to understand common design patterns and KISS
(Keep It Stupid Simple), DRY
(Don’t Repeat Yourself), and SOLID
principles. At this stage, you may also be interested in trying out other programming languages or frameworks to enhance your skills and experience.
If you really put effort, then one day you’ll definitely become a Senior Java Dev. What to expect in this role? Our article What It’s Like to Be a Senior Developer. A Short Guide to the Role
reveals all the secrets. You may be surprised that Seniors are not only writing perfect code but also mentoring Juniors and Middles to build a solid team. They care for performance, and one of the most valuable skills of Senior developers are strong social skills. Seniors know that working in IT is not just about communicating with the computer in front of you. It’s also about communicating with people surrounding you.
