What Skills Java Developers Can Learn In 2022?

Learning these important skills can help Java developers build a strong, professional career.

Learning is one of the exciting and biggest challenges in a software developer's career. Since technology is evolving every other day, today's new technology becomes an old one pretty quickly. Java is one such programming language regularly used in the software development industry. On 23rd May 2020, Java completed 25 years. But, this programming language is still very much in use.
As Java keeps on evolving, job opportunities for Java developers are also plenty in the market. The huge spike in candidate requirements for Java jobs in USA shows the demand for Java developers. But with new trends emerging every day, it becomes difficult for software developers to keep up with the changes.  And, that is the biggest challenge for any programmer.

The latest hiring trends show that Java developers who are fluent in AWS, Git, Spring, and Docker are in demand. Therefore, when planning a Java development career, ensure that you update yourself with all these trending technologies.

Top Tech Skills For Java Developers

Technology is changing rapidly. Every programmer has to keep themselves updated with the current technologies. With the changing trends, there will be a huge demand for developers too. So, as a Java developer, you need to know certain things that can help you build a good career in Java.
1. Spring
Spring is a powerful framework that supports all web applications that use Java as their programming language. Even though Spring Boot is a new framework, knowledge in Spring is a must-have skill for Java programmers. Spring offers you a dependency injection that helps make testable code writing much easier. Loaded with several libraries, utilities, and templates, it also helps in making daily Java programming better.
2. Java Versions
Java is a vintage language. However, there are new versions released quite often. So, if Java development is your main skill, you will have to keep it updated. You can do so by learning the several versions from 9 to 15. Learn all the new features added, deprecated, and improved in Java versions 9 - 15.
3. Spring Boot
Spring Boot is another top recommendation that every Java developer should learn. Spring Boot uses Spring's principle of simplification and makes Spring-based work much easier. With Spring Boot, it becomes easier to develop Java applications. It also has features like auto-configuration to help configure the Spring application. By using Spring Boot, you can save time on bootstrapping the Java project.
4. RESTful Web Service
Implementing scalable RESTful web services is another major and useful skill for Java developers. This is because there aren't many web applications that do not use REST API. This is one such skill that is much in demand in the Java world.
5. React JS or Angular 2+
React JS, or Angular 2+, are Javascript frameworks for user interface development. A Java developer must know these two important technologies. Having enough knowledge about these technologies can change the way you develop web apps. Throughout your Java career, you might have used JSP, Servlet, and jQuery. However, trying Angular or React can help you work much better.
6. DevOps
Knowledge in DevOps tools, like Jenkins, Gitlab, Bamboo, etc., are must-have skills for a Java developer. Most organizations have now adopted the CI/CD model to improve the quality and speed of their development cycles. Thus, it helps a Java developer to be hands-on on some of these tools.

Update Yourself With New Technologies

7. Docker And Kubernetes
Docker and Kubernetes can be termed as a lethal combination. Docker abstracts environment specifics needed to run your code. With containerization, you can create/replicate any development environment without having to worry about server setup and installations. It can help in putting libraries, installing Java, setting PATH, and many more. Docker is quite useful in the process of software development and deployment.
Kubernetes enables the orchestration of Docker containers. Having proper knowledge about Docker and Kubernetes is important for a brilliant career in Java. Every development team in the industry, no matter whether they are small or large, uses Docker and Kubernetes. As per reports, by 2025, around 80% of the worldwide organizations will be using Docker and Kubernetes.
8. Unit Testing
There are several new tools and frameworks available for Java programmers to perform different forms of testing. Using the new frameworks, you can unit test your application or run integration tests. For example, there are Cucumber and Robot frameworks for the automated integration test. There are also tools such as PowerMock and Mockito for mocking objects and JUnit for unit testing.
If you are a Java developer, you should invest some time in learning unit testing skills. This improves your coding skills and helps you become a professional developer.
9. Microservices
Microservices are an extension of the RESTful web service. For the last couple of years, the demand for microservices has gone up. The major advantage of microservices over traditional monolithic applications is their simplicity. With microservices, you can make the development and maintenance of applications much easier than any other monolithic application. This is because the microservices divide the application into smaller, composable fragment sets. In the Java world, there are excellent opportunities to build Microservices with the help of Spring Cloud and Spring Boots. This is why the demand for Java developers with microservices knowledge is high for tech USA jobs.
10. Cloud Computing
Many companies are opting for cloud computing nowadays. This is because the Cloud helps in saving costs and offers better scalability. As new cloud platforms emerge, it is imperative that modern Java applications will be built on the Cloud. Being hands-on with cloud platforms, like Google Cloud Platform ( GCP), Amazon Web Service ( AWS), or Microsoft Azure, can help you become a better Java professional. Hence, it is important to learn Cloud computing for a better career in Java.
11. SQL
SQL is another major skill Java programmers need to acquire. SQL is mainly used to analyze data that is stored in the database. Therefore, SQL is a critical tool, and as a Java programmer, you must have enough knowledge about the same.
12. SOA
Service Oriented Architecture (SOA) is a software design style. It offers services to other components through the protocol. Service-oriented architecture can be similar to microservices. This is because, like microservices, SOA also is independent of vendors, technologies, and products. However, the major difference between SOA and microservice is the size. Compared to SOA, microservices are quite smaller in scope and size. Since real-world applications are more complex, SOA architecture is a better option. This is the reason why there is a huge demand for Java developers with SOA skills.
13. Apache Spark And Kafka
Knowledge of these two technologies is a must-have for a Java developer. Apache spark offers an application interface for many tasks, like scheduling, dispatching, basic input, and output functionalities. The features of Apache spark include advanced analytics, integration, speed, and real-time stream processing. It also supports multiple languages.
Apache Kafka offers an open-source stream processing platform. It also offers a storage layer that is important for logging transactions. Apache Kafka features include reliability, zero downtime, durability, high performance, replication, and data transformation. Hence, having good knowledge of these two technologies can help you build a better career n Java.
Technology is changing rapidly nowadays. Therefore, it is important to keep yourself updated about the new things happening in your area of expertise. By learning these new trends, you can have a bright career as a professional Java developer.
