To help you with what tools you can learn in 2019, I have come up with this list of 10 essential tools for Java developers that I am going to share with you guys in this article. In the past, I have shared some useful testing tools for Java programmers, and this article is an extension of that, as it covers much more than automation testing tools. With a solid become a java developer understanding of SQL, you will be able to understand the store procedure and query DB, and as a result, improve your troubleshooting. All developers need to be able to determine if application issues are in your code or on the database layer. So mastering the basics of CRUD operations, joins, aggregations and indexing will help you a lot in your career.

• As I said, Technology changes at a rapid speed, and the biggest challenge for programmers are to keep themselves up-to-date.
• The bottom line is that you must understand the networking basics to understand, develop, and support your application.
• While Java development is a team sport, Java developers complete many of their daily tasks alone.
• This will not only boost your profile but also make you eligible for many Java developer jobs that need good Spring, Hibernate, and Spring boot skills.
• This appears to be the only version control system that is still developing (and for which the surrounding infrastructure is still developing).
• Earlier, I have shared The Complete Java Developer RoadMap and today I am going to share the most essential Java frameworks you can learn.
• Eclipse remains one of the most popular Java IDEs in the world, largely because of its flexibility, as it’s free to use (open-source), and the promotes a strong community.

For CI/CD pipelines, you can learn Jenkins or Team City (and even better to read about clouds in Azure Pipelines). Companies are more and more often facing leaks of valuable information. Such incidents lead to huge losses, both financial and reputational. Enterprises are ready to invest serious money into protecting their data, applications, and infrastructure. Many major companies, including us, already have divisions to test their software for vulnerabilities.

The main problem I face when hiring a good developer is simply making sure that their code can be maintained by someone else. More often than not, programmers like to write code that only they can easily maintain, and that can be quite costly to an employer like me. Java has a vast ecosystem of libraries and frameworks that can significantly simplify development tasks. Utilize popular libraries such as Apache Commons, Gson, or Jackson for common operations like file handling, JSON parsing, or database access.

If you’re not afraid to dig into related areas, can pick up new tools on the fly, and solve problems where they appear, you’re the right person for this role. In most cases, microservice architecture is inextricably linked with the use of Docker containers for builds and deployment, and with the use of a container manager when the number of services is relatively large. One of the most successful solutions for container management today is Kubernetes — an open-source solution from Google that is now being jointly developed by several major vendors. This platform has also become the basis for other more complex solutions. For developers, this means that knowledge and experience with the main cloud services will be key – and even more important than knowledge of Java itself.

What will impact Java development in the coming years?

As developers must update programs to ensure they’re functional and secure, you need to develop regular updates. You will need to plan, design, test, deploy, and collect user feedback on the update to build efficiently. If you work in a large business or busy industry, you may need to manage multiple updates simultaneously. Throughout your time as a developer, you will continuously develop code in Java. You may use this code in a new project, ongoing updates for an existing project, or bug fixes.
