There are numerous tools that exist within the Java world, ranging from a renowned day like Eclipse, NetBeans, and IntelliJ plan to JVM identification and observation tools like JConsole, VisualVM, Eclipse Memory instrument, etc. This article comprises of general tools, that are applicable to each reasonably Java developer, e.g. each core Java and net developers.
One such tool is JIRA, which could be a must-know for skilled developers, particularly if your team is following Agile practices like Sprint, Scrum, and Kanban. JIRA provides all the tools you wish to manage your Agile comes.
Git is one of the more essential tools for Java programmers. It is a free and open-source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
Git is easy to learn and has a tiny footprint with lightning-fast performance, but unfortunately, I haven't worked on Git extensively. I have used Git to download open-source projects and examples from GitHub using Eclipse, but I have yet to master the Git command line that's why I have set this as a goal to learn in 2019. I have already bought the Git Ultimate course from Udemy for just $10 on their last flash sale and I am looking forward to learning it as soon as time permits.
I generally buy a lot of courses when they run a flash sale, and then, I just take them whenever I have free time. Since Udemy gives you lifetime access, of course, you can learn at your own pace. However, if you prefer free resources, then you can also see this list of free Git courses for programmers. They are actually quite good as compared to some other paid courses.
Docker is an open-source tool for automating the deployment of applications on the cloud or physical servers. It allows developers and system admins to build, ship, and run distributed applications, whether on laptops, data center VMs, or the cloud. Docker works in collaboration with the cloud, Linux, and Windows vendor and many companies focusing on IT automation, Docker is nicely poised to take advantage of that.
If you are thinking to learn a new technology in 2019, invest your time in Docker for the Absolute Beginner course, which teaches Docker with hands-on coding exercises. If you like to learn from free resources, e.g. books and courses, then you can also check out this list of free Docker Courses for Java developers, which contains a lot of useful information.
Jenkins is an open-source automation server written in Java. It helps to automate the non-human part of the software development process, e.g. compiling projects, running unit tests, integration tests, and generating documentation and uploading artifacts on both local and remote repository.
It's one of the most popular tools for continuous integration and implementing continuous delivery in your project. If you have yet to start with Jenkins, then there is no better time than 2019 and no better course than Master Jenkins CI for DevOps and Developers; you will hit two birds with one stone. If you like free stuff, then I also have a collection of free Jenkins courses that you can check out to start learning Jenkins in your spare time.
Selenium is one of the best software-testing frameworks for web applications. It provides a playback tool for authoring tests without the need to learn a test scripting language. Java developers can use Selenium to test their HTML and JSP files.
It also provides a variety of tools and libraries for web browser automation. If you are in automation and testing space, then Selenium is must for you. If you decide to learn Selenium in 2019, then the Selenium Web Driver with Java is a good course to start with. If you prefer free resources, e.g. free online courses, then you can also check out this list of free Selenium Web Driver courses for Java developers to start with. These are actually some paid courses that their instructor made free for promotional and educational purposes.
If there is one language that Java developers should learn in 2019, then it should be Groovy. Why? Because it complements Java. You can do a lot more in your Java project using Groovy than just sticking to plain Java.
You can use it write build scripts, test scripts, and even use popular frameworks like Gradle and Spock. By the way, for those who don't know, Apache Groovy is an object-oriented programming language for the Java platform. It is a dynamic language with features similar to those of Python, Ruby, Perl, and Smalltalk, and it extends Java by providing concise and powerful syntax. If you are absolutely new to Groovy, then The Complete Apache Groovy Developer Course is another good place to start. If you like to learn from books rather than online courses, you can also take a look at this list of Groovy Books.
