Java Programming: Once a Rock Star, Always on Top

Looking back at the history of programming languages, Java has always had a special place in the hearts of back-end developers.

Most of them enjoy Java programming because of its simplicity, platform independence, security, range of available resources, and other features. These advantages significantly contributed to Java’s popularity—there are now more than 7 million Java developers worldwide.

Every year, StackOverflow releases its Developer Survey for tech enthusiasts all around the world. Looking back at the results from 2019 and previous years, one thing is clear – Java is always a Top 5 Most Popular Technology.


So, What are the New Java Trends?

The tech world shows no signs of stopping, so we suggest you closely watch these latest trends in Java to keep up with it.

  • Let Java 8 Go

We know that you hold Java 8 dear to your heart, but it’s time to move to Java 11. Very soon, Oracle will no longer support Java 8, so it’s up to you to download and install newly added features and encourage your team to take this step now (if you haven’t already done it). And remember, 2020 is the year when Java 14 will be knocking at our doors.

  • Keeping Up with DevOps (Docker or Jenkins)

By 2022, the DevOps market will reach $6.6 billion, so it’s fair to say that DevOps practices and technologies will shape the tech market. Are you eager to have faster and more efficient deployments? If so, applying automation should be on your agenda.

  • Git: Get It Together

Add one more item to your list. Trust me, you’ll thank me later! Many companies have already started migrating SVN and CVS projects to Git, so it’s about time for everyone who takes Java programming seriously to start mastering Git.

  • Spring into Action

You’ve probably already been using the Spring Framework, and are familiar with its basic concepts. Now is the time to upgrade your Spring Framework skills. In the last couple of years, there have been some important releases for Spring, Spring Boot, and Spring Security. Today, it seems that everyone is obsessed with leveraging the Cloud for development. When it comes to the Cloud, Microservice architecture has a special place in the Java programming equation.

  • Tried and Tested: Powerful Java Tools

In terms of separating the beginners from experienced professionals, automation testing skills make a difference. For any project it’s beneficial to have a developer who can write unit tests and has a deep understanding of various unit testing frameworks, libraries, and tools: Junit, NUnit, TestNG, Jmockit, EMMA, Selenium, REST-Assured, Spock framework, and others.

  • Big Data and Java: A Match Made in Heaven

Java developers have access to a wide range of open-source big data tools: Apache Hadoop, Apache Spark, Apache Mahout, Java JFreechart, Deeplearning4j, and many more. Most Java developers can easily take on a new big data tool since it’s like learning a new API, plus some of the core modules of big data tools are written in Java.
