Tools for Experienced Java Programmers


1. Git

I think Git and Github should be the most essential tool all Java the programmer should learn and master. I know many of you already know Git but those who are still working in SVN and CVS seriously consider learning Git and Github this year.

There is no way you can avoid Git anymore, even if you don't use it in your current project. It has become a standard for source code repository and most of the the new development is using Git.

If you are a beginner I suggest you check out the GitHub Ultimate course to start with.  Even if you know Git, you can still learn things e.g. Git command line to further improve your knowledge. All the time and money you invest in learning Git will serve you for a long time.


2. JIRA

After Git, I think JIRA is the second most important tool for any Java developer or say any programmer out there. It has quickly become the #1 Planning and bug tracking tool on many organizations.

If you are working in an Agile team like following Sprint schedules and doing Scrum meetings then JIRA is even more important. With all its capabilities to support Agile methodologies, its a must know a tool for an Agile team.

You can even impress your manager and colleague by knowing JIRA in-depth e.g. You can help your team to create Sprint dashboard. If you are serious about learning JIRA in 2019, then Learn JIRA with real-world examples is a great course, to begin with.


3. Maven

This is another essential tool for Java programmers which help you to build and manage a Java project. It's been there for quite some time and a good chance is that you already may have heard about Maven or using it in your project.

It not only help you to build your project e.g. compile source files but also run your unit test and can deploy your artifacts or deliverables to live environments. It also helps with managing dependencies e.g. all the third party JAR files you use in your projects.

Without Maven, this can be really a nightmare. In short, all Java developers should know Maven in 2019 and if you are looking for a good course to start with, you can check out Apache Maven: Beginner to Guru course from Udemy, one of the best course to learn Maven.



4. Jenkins

Jenkins is another essential tool for Java developers, particularly those are hoping to become a DevOps professional. This is a continuous integration tool, which means it can continuously build, test and deploy your project.

In our case, Jenkins automatically runs the build every time someone check-in their code. IT also has scheduled nightly and hourly build to automatically build and test our project.

If you are a senior Java developer e.g. someone with more than 5 years of experience and you don't know Jenkins then you should seriously consider learning it. If you decide to learn Jenkins, the Learn DevOps: Jenkins CI/CD with Docker is a fantastic course to start with.


5. Selenium

This is another great tool for Java developers, particularly Java web developers. Selenium is a tool for web browser automation, which means you can test your web pages like both JSP and static pages written using HTML and JavaScript using Selenium.

It provides a playback tool for authoring tests without the need to learn a test scripting language. It's becoming very popular nowadays and that's why learning it not only help you to write better code but can make you more valuable.

If you are serious about learning Selenium in 2019 I suggest you start with Automated Web Testing with Selenium on Pluralsight to learn how to write an automated test for a web application.


6. Docker

Docker is a tool that allows users to quickly assemble apps from components and work collaboratively. If you are working on web development e.g. developing and deploying applications for cloud then Docker is an essential tool to learn.

This is appropriate for managing containers of an app as a single group and clustering an application's containers to optimize resources and provide high availability. If you are serious about learning Docker then I suggest you to first go through Docker and Kubernetes Complete Guide before using it in your project.

How to convert Stream to Set using java

In Java 8, Stream is one of the most important class as it allows a lot of useful functional operations e.g. filter, map, flatmap, etc on a collection of object. Hence, going forward converting a Collection to Stream, performing operations and then converting the result back to different Collection classes like List, Set, and Map will be a common task.  You can convert a Stream to Set by using the Collectors.toSet() method. Since Set doesn't allow duplicates and doesn't provide any ordering guarantee, any duplicate elements from Stream are lost and ordering is also gone. Set<Integer> aSet = input.stream().collect(Collectors.toSet()); There are no implementation guarantees provided for the Set returned by collect method here. You can't assume it a HashSet, but it will something which implements Set interface. Also, the size of Set will be less than or equal to a number of elements in the final Stream because duplicate elements are lost when you covert Stream...

Java Concurrency Method basic example

What is a Thread A Thread is a lightweight Process. Any Process can have multiple Threads running in it. For example in a web browser, we can have one thread Which will load the User Interface and we can have one more thread which will actually retrieve all the data that needs to be displayed in the User Interface. What is Multi-Threading Multithreading enables us to run Multiple Threads Concurrently. For example in a web browser, we can have on the thread which handles the User Interface and in Parallel, we can have one more thread which is fetching the data to be displayed. So multithreading improves the responsiveness of a System. What is Concurrency Concurrency in the Context of Threads enables us to run multiple Threads at the same time. Here Java concurrency example . But do the Threads Really run at the same time? Single Core Systems The Thread Scheduler provided by the JVM decides which Thread runs at any given time. The scheduler gives a small t...

How to Learn Java Effectively

To code or not to code? It seems that you’ve made your choice in favor of the first option. Programming is a great field for professional growth, It gives you an opportunity to take part in interesting projects and work wherever you want. The only obstacle that restrains many beginners from starting a new career is the lack of understanding of how exactly should they learn to code.  What’s more important is that even the best universities can’t fully provide the education, which will guarantee a stark career as a software developer. The thing is that programming is too dynamic and flexible: once you start learning, you better do it for the rest of your life. Some programmers say, that they’ve been trying to learn how to code a few times before finally reaching their goal. Yes, we all learn through mistakes, but you’ll be surprised how many common lapses are there in mastering this skill. Troubleshooting your learning experience If you’re determined to learn Java programmi...
