There are many tools in the Java world, starting with well-known ides like Eclipse, NetBeans, and IntelliJ IDEA, to JVM analysis and monitoring tools that Java developers should know about, such as JConsole, VisualVM, Eclipse Memory Analyzer, etc.
1. JIRA
Atlassian’s JIRA is one of the most important tools in agile development today. It is used for error tracking, problem tracking, and project management. If you follow agile development methods, such as Sprint and Scrum, then you must understand JIRA. It allows you to create Spring loops and track the progress of software development.
JIRA is a popular Java-based management system. Atlassian offers defect tracking services free of charge to many open source projects, so it is much more recognized and easier to use in the open source space.
2. Git
Git is another must-have tool for Java programmers. It is a free, open source distributed version control system designed to handle versioning of projects from the very small to the very large quickly and efficiently. Git is easy to learn, takes up little space, and has superior performance.
Git was originally developed to aid in the Linux kernel development process, but it has been found to be used in many other free software projects.
3. Jenkins
Jenkins is an open source automation server written in Java. It helps automate software development, such as compiling projects, running unit tests, integration tests, generating documentation, and uploading artifacts to local and remote repositories. Mainly used for:
● Continuously and automatically build/test software projects such as CruiseControl and DamageControl.
● Monitor some scheduled tasks.
It is one of the most popular tools for continuous integration in projects. If you haven’t already started using Jenkins, start now.
4. Selenium
Selenium is one of the best software testing frameworks for Web applications. It provides a playback tool for authoring tests without having to learn the test scripting language. Java developers can use Selenium to test their HTML and JSP files.
It also provides various tools and libraries for Web browser automation. Selenium currently exists in two versions, one called Selenium-Core and the other called Selenium-RC. The latest Java interview questions to share with you.
5. Groovy
Groovy is an agile jVM-based development language that combines many of the powerful features of Python, Ruby, and Smalltalk. You can use it for build scripts, test scripts, and even popular frameworks like Gradle and Spock.
6, Spock
Spock is a testing framework suitable for Java and Groovy applications. Thanks to its JUnit running program, Spock is compatible with most ides, build tools, and continuous integration servers.
If you want to improve your unit testing skills, it’s always a good idea to spend more time learning Spock.
7. Maven
If you’re an experienced Java developer, you’re familiar with Maven. Apache Maven is a build and project management tool that can be used to manage project generation, reporting, and documentation based on project Object Model (POM) concepts.
Another useful feature of Maven is dependency management. Since we use a lot of third-party libraries in Our Java projects, manually managing each JAR and its dependencies can be cumbersome. Maven helps you out by automatically downloading the correct JAR for you
8. Gradle
Gradle is a project automation build tool based on Apache Ant and Apache Maven concepts. It is also the default build tool for Android.
It introduces a Groovy-based domain-specific language (DSL) rather than the XML Apache Maven uses to declare project configurations, which facilitates the configuration of project dependencies and user project customization
Why choose Gradle in Ant or Maven? Because it combines the best features of other build tools, such as Ant’s flexibility and control, Ivy’s dependency management, Maven’s configuration and plug-in conventions, and the ability to use the Groovy DSL on Ant. This makes it the best build tool for Java projects.
9. Docker
Docker is an open source application container engine that allows developers to package their applications and dependencies into a portable container and then distribute them to any popular Linux machine, as well as virtualization.
Containers are completely sandboxed and have no interface to each other (like iPhone apps). It has almost no performance overhead and can easily run on machines and data centers. Most importantly, they don’t rely on any language, framework, or packaging system.
10. Linux
Linux is a free and open source UniX-like operating system that has played an important role in your career. Every Java developer should learn Linux.
If there’s anything you haven’t learned yet, don’t miss it.
