Java Developers Should Learn this Top 7 Techs in 2020


One of the biggest challenges that developers face is keeping up-to-date with all of the newest releases. This means that new versions and accompanying technologies of favorite programming languages are constantly being released and developers must take the time to learn them.

With Java continuing its reign as one of the top programming languages to learn this year, both independent or freelance developers and those who are a part of a Java development company must stay updated on this technology and the trending topics surrounding it.

Java Developers Should Learn this Top 7 Techs in 2020

Below are just a few of the most useful and popular accompanying technologies that a Java Developer must learn:

  1. Git
  2. Git is a free, open-sourced distributed version control system designed to handle projects of all sizes with efficiency and speed. Although Git and Github have already been around for quite some time, many Java developers have yet to master this tech. They may have a bit of experience with it while using Eclipse or downloaded projects from Github, but aspects such as error management and reverting changes may prove to be rather difficult. With many companies migrating their projects from SVN to Git, 2020 is the year to master this tech to work alongside Java.

  3. Jenkins
  4. Originally derived from Java itself, Jenkins is an open-source automation server written in Java. It automates the software development process with continuous delivery and integration while various version control tools are also supported. This technology has released many plugins so that it can integrate well with coding projects written in other programming languages.

  5. Groovy
  6. If there is one technology that every Java programmer should learn in 2020, it’s Apache’s Groovy. Built to complement Java, this technology helps elevate projects as an object-oriented programming language for the Java platform. It allows developers to write and build scripts, run tests, and utilize popular frameworks such as Spock and Gradle. It is a dynamic language that includes features that are similar to Python, Ruby, and Perl, but it extends Java by offering concise and compelling syntax.

  7. RESTful Web Services
  8. “REST” stands for Representational State Transfer. The REST API communicates within web services development and provides an architectural style that is applicable to Java projects. It helps to increase the working output of web services, which is a highly desirable thing for developers who work with Java. The client-server based architecture of this program provides operations such as server hosting, management, and delivery while acting as a shared computer model for shared resources. Additionally, it provides scalability, flexibility, and the ability to choose any technology or platform.

  9. Unit Testing
  10. Many new frameworks and tools have become available for Java programmers to unit and integration test their applications. This includes PowerMock and Mockito for the mocking of objects, Cucumber for automated integration testing, and the new JUnit 5 Library. When Java developers take the time to upgrade their unit testing skills, they are able to improve their overall coding abilities, which should make this a top priority for every developer this year.

  11. Apache Spark and Kafka
  12. These are two technologies that should be top priorities for Java programmers in 2020. It provides an application interface for tasks such as basic input/output functions, dispatching, and scheduling. Apache Kafka then provides a platform for stream processing that is also open-source.

  13. DevOps
  14. DevOps has already gained a lot more traction in 2020 compared to last year and years before as more companies move to this approach. DevOps is helpful for software development operations as it reduces the overall lifecycle of systems development and delivers business objects along with many features and updates. When working with Java, it improves the relationship between Information Technology Operations and Development by bettering collaboration and communication.
