Java Developer Skills - 2021

DevOps

Java DevOps is simply applying DevOps practices and philosophies to Java app development. That means that compartmentalized teams are no longer needed when creating Java applications. DevOps is the practice that encourages communication, collaboration, integration, and automation between software development.

DevOps is very vast and you need to learn a lot of tools and principles and that’s what overwhelms many developers but you don’t need to worry. I have shared a DevOps RoadMap which you can follow to learn and master DevOps at your own speed.

Git

In Git, the repository is like a data structure used by VCS to store metadata for a set of files and directories. It contains the collection of the files as well as the history of changes made to those files. Repository in Git is considered as your project folder.

Since now most of the companies are migrating their projects from SVN, CVS to Git, its high time to learn and master Git.

If you are in the same thought and want to learn or improve your Git skill in 2021, kindly do learn in online. This is one of the most popular version control systems.

Java 9 -15 Features

Java is, at times, called a superior language, but is still very much in use with new releases launching often. If Java development is your midst skill then what you’ll want to do is stay abreast of the features being added, improved, and deprecated.

Thus, you should learn the new features of Java Versions of 9 to 15, as it increases its algorithm day by day with some differences and versatility.

So, just learn some innovative and other features through joining an advanced java course with certification with frameworks which will enhance your way of approach in career.

Spring Framework

Spring is a powerful, lightweight framework used for application development. In other terms, you can say that a spring framework is a well-defined tool that supports a variety of web applications using Java as a programming language.

Spring Framework is an open-source Java-based framework used to create a micro Service. It is developed by Pivotal Team and is used to build stand-alone and production-ready spring applications.

Dependency Feature of the Spring Framework allows you to develop loosely coupled applications. Therefore, the unit testing of these loosely coupled applications becomes easier. This also allows the developer to swap out some of the modules according to its need.

Unit Testing

Another area which you to improve in this 2021, There are a lot of new frameworks and tools available for Java programmers to unit test and integration test their application e.g. Mockito and PowerMock for mocking objects, Robot Framework, and Cucumber for automated integration test and of course the new and shining JUnit 5 library.

Unit testing means testing the smaller units of your application, like classes and methods. The reason you test your code is to prove to yourself, and perhaps to the users/clients / customers, that your code works.

Spring Security

Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto degree for securing Spring-based applications. Spring Security is a framework that focuses on providing both authentication and authorization to Java applications.

This is the third major upgrade on Spring Eco-System. The 5th version of the popular security framework has several bug fixes and a major OAuth 2 module, which you just can’t miss.

Spring Boot

This is another framework recommendation, that every Java developer to learn in 2021 and going forward. Spring Boot took Spring's philosophy of simplification and made it easy to work with Spring itself. Just like Spring makes it easier to create a Java application, Spring Boot makes it easier to create a spring-based Java application.

Features like auto-configuration take away most of the pain correlated with configuring the Spring application. Similarly, starter POM features grouped commonly used dependency into simple reusable POMs.

Join now in SpringBoot Course of Java and learn the advanced training and frameworks, also learn step-by-step guides for everyday things a Spring Boot developer needs to know.

To conclude, these are the skills a Java developer should be aware of in this year of 2021. That's all about the 2021 Java Developer Skills. This is an excellent resource to learn Java in 2021 and become a better Java developer. We have kept it simple so that most of the people can follow it.
