Java has stood the test of time as one of the most sought-after coding languages of the industry.

The language was first released in 1995, providing the ability to create complete applications that may run on a single computer or be distributed among servers and clients in a network. Java has evolved over the years, and as it continues to evolve, job opportunities for Java developers will remain plenty in the market.

Java has been the dominant language over the past two decades, and shows no sign of slowing down. However, predicting the future of Java is certainly not a science. Changes within the language, whether it be within the supporting ecosystem, or within development as a whole, can change the landscape overnight.

With new trends emerging daily, it becomes increasingly difficult for software developers to keep up with the changes. So, let’s take a look at the most popular trends to watch for the new year!

1. Java / Spring Framework
If you’ve worked with Java, I’m sure you’re familiar with the Spring framework (it’s one of the most popular frameworks in Java!). It allows for a wide variety of users; from streaming platform or e-commerce stores, to insurance or banking platforms. The Spring framework is very user-friendly, so make sure to keep updated with the latest version, as it is in high demand now. It’s an excellent solution for building applications in Java as it involves the microservices, complex data processing systems or safe and fast web apps. The popularity of Java has increased immensely with the use of the framework, along with its new updates.

2. Cloud Technologies
Did you know that the widespread digital transformation activity within corporate and public sector organisations has led to a rise in Australian investment in cloud-based infrastructure services by more than $450 million in a year?
Many companies are now opting for cloud computing, because the Cloud helps in saving costs and offers better scalability. As the popularity of cloud platforms continues to grow, it is imperative that modern Java applications are built on the Cloud. Hands-on experience with Amazon Web Services (AWS), Microsoft Azure or Google Cloud Platform (GCP) is essential in the industry today, especially the market leader, AWS.
Java is widely used for developing AWS applications, since it is well suited for distributed systems and systems that require data protection. On the back end of the AWS platform, you will find a lot of Java. In saying this, it is evident that the rapid growth of cloud technologies in recent years will lead to an increase in demand for Java Developers with Cloud experience.

3. Serverless Architecture
Serverless architecture can be defined as software used for design patterns to build and run apps controlling infrastructure and can be done merely with coding. It allows you to make a robust serverless system and focus on the core product of the operating servers without the stress of managing it. A huge benefit of using serverless architecture is that it won’t be necessary to set up machines or network configurations, hence why it will continue to be a universal trend in 2022.
4. Integration Testing
Testing is an essential procedure that must be done every time you write code. The purpose of testing is to help reduce errors or misprints, while also showing that the code can work successfully. The point is to not waste time on searching or rewriting mistakes. To reduce the time that spent on creating tests manually while building an app in Java, the following frameworks or tools are commonly used:
  • Cucumber,
  • Junit
  • Robot Framework
  • Selenium
  • Mockito
  • Hamcrest
5. Artificial Intelligence
Java is typically connected with algorithms - it is popular with app development companies that work with artificial intelligence. Java is an appropriate language for creating AI apps, allowing a developer to code different types of algorithms. Java will continue to grow and offer a large amount of resources that can help connect Machine Learning with AI, leading to forming apps that will speed up business growth.

6. Big Data
Data collection is essential, as there is more and more data generated every day, which has to be stored. That is why organisations require big data calculations.
Java is the preferred language for big data projects because it’s a reliable language to use, since it has open-source tools including:
  • Apache Mahout
  • Apache Hadoop
  • JFreechart
  • Deeplearning 4j
Another tool that can be used is Cassandra, which is an open-source tool that will continue to function even if one server fails.

In summary, although there is a myriad of languages on offer, it is universally acknowledged that the strengths and benefits of Java means that it will continue to dominate for years / decades to come. Java has continued to evolve and adapt over the years, and will remain the mainstay for top developers moving forward.
