You should know many things if you wish to work effectively on Java projects as a developer in today’s competitive environment. You’ll need a variety of abilities, and which ones you’ll need will depend on the position you’re applying for.

Are you a Java programmer or a working professional interested in making the switch? Also, are you a working Java developer who wants to advance your career? Then this post is for you; there are certain advanced technologies that [Java developers](https://www.infiraise.com/hire/hire-java-developer/) should be aware of.

## Technologies that Java developers should be aware of


## **Spring Boot 2**

Spring Boot 2 is a new version of the Spring Boot framework. This Framework is in charge of the control, whereas Spring Boot produces a standalone solution with a standard configuration.

**Key Features are** 

- It Provides complete security and technology support.
- No code generation is required for XML configuration.
- To reduce the build configuration, provide dependencies.
- Deploy Undertow, Jetty, or Tomcat directly.

## Git

Git is a vital tool for JAVA developers, and it is recommended that every JAVA developer learn it. This version control system may be used to manage any number of projects. It is a completely free open-source system. It emphasizes non-linear workflows, data integrity, and speed.

- This distributed extension aids in the creation of a duplicate of the development history.
- It has a toolkit-based design that gives a well-defined model for linking approaches.
- Toolkit-based design aids in the reduction of the composite part.
- Git has strong support for non-linear extension, with scaling and branching being two key features. Git is a great tool for non-linear development.
- Huge project management that is well-organized: A locally stored repository aids in the transparent management of large projects.

## Jenkins

Jenkins is an open-source automation Continuous Delivery and Integration tool that is derived from JAVA programming. It automates the software development process and supports many version control tools.

## Docker

Docker is a Linux-based language created in the Go programming language. It’s also a must-have for aspiring Java developers. Docker provides containerization-related tools. It was also released in a stable state at the end of 2018. It is in charge of managing the container, or group of software programs.

## Unit Testing

Unit testing is an essential skill for JAVA developers that you should learn in the coming year. For those working in Java, towards integration and unit testing, there are several tools and frameworks, for example, Cucumber for automated integration testing and the Robot framework. Mockito is also a tool that will help you use your unit testing skills.

## Java 10, 11, or maybe 12

Java is one of the most widely used languages in the world and knowing it is a must for JAVA developers. REPL is what it’s called (Real Evaluation Print Loop). The Java Shell is covered in detail in Java 9. Java 9 executes and tests well-known Java features such as declarations, objects, interfaces, and classes. You can alternatively upgrade to a newer version of Java, such as Java 10, 11, or 12. Java 12 is the most recent version of the Java programming language.

## DevOps

DevOps was also one of the most important skills for Java developers to learn. It is a powerful method of managing software development. DevOps is a strategy for software development operations that reduces the development cycle of a system while still offering updates, features, and other benefits to corporate objects.

**Key Features of DevOps are**

- Very fewer steps
- Support for existing systems
- Using system translation
- Deploying a DevOps toolkit

## Groovy

Groovy will be one of the most important tools for Java developers to learn. Java is praised by Apache Groovy since it supports Java syntax. One of Groovy’s best qualities is that it can be used both statically and dynamically.

## Apache Spark and Kafka

Apache Spark and Kafka are two must-have technologies for Java developers, both of which were released in a stable state at the end of 2018. Spark is a free and open-source framework for cluster computing.


**Features of Apache Spark are** 

- Real-time stream processing
- Integration
- Advanced analysis
- Multilingual support
- Speed

**The main features of Apache Kafka are**

- No downtime
- High performance
- Reliable
- Robustness
- Data conversion
- Replication
- Docker

We’ve reviewed the most important skills for Java developers to learn to enhance their careers. This does not imply that Java developers should master all of the abilities listed above. The talents are evaluated by India’s top [Java app development](https://www.infiraise.com/develop/web-app-development/java-development/) businesses, as previously said.
