Java is one of the oldest and most widely used programming languages for software development. For businesses that handle a huge user base, it is the most favored option. Each year, experts predict that Java will fade away, but it comes back stronger each time with new features and robustness. With the current advancements in IoT, AI, and Big Data, the usage of Java for Data Science applications is on the rise. According to the most recent Java trends for 2021, it is predicted that this programming language will become the dominating platform in the software development business over the next several years. Irrespective of whether you are a developer or someone who wants to invest in Java web development, you must be aware of these trends of Java technology.

1. Serverless Architecture

A trend that is likely to become more common in the future is the shift to a serverless architecture. It's a cloud-based solution that allows you to concentrate completely on code rather than infrastructure.  You don't have to upgrade operating systems, scale the program, set up computers, or configure the network when you use serverless architecture. You'll also get the benefit of more flexibility and lower operational expenses, which will result in faster value delivery.

2. Integration Testing

Testing is an important step in the code writing process for software development. It aids developers in reducing typos and mistakes while also demonstrating that they have a working code.  Developers can save time in this manner, which they can use towards rewriting or looking for errors. When developing a sophisticated Java project, however, developers may have to spend a significant amount of time manually writing tests.  To expedite the process, frameworks, test libraries, and tools such as JUnit, REST-Assured, Selenium, etc. are now available to developers.

3. AI-Powered Business Solutions

Java's popularity has surged among artificial intelligence app development firms due to its characteristics such as low maintenance, transparency, and portability. Because AI is linked to algorithms, Java is a good language to use for developing AI-driven apps since developers can code a variety of algorithms using Java.  Furthermore, Java provides a wealth of tools for connecting Machine Learning and Artificial Intelligence, resulting in the development of apps that help businesses expand faster.

4. Spring Framework

From online shopping and streaming platforms to banking and insurance platforms, the Spring framework can be utilized in a variety of ways. It is suitable for developing a backend Java Enterprise Edition platform for Java app development. It's also a great option for creating Java-based apps for a company. Due to its lightweight nature and ease of implementation, Spring's popularity is expected to grow even more in 2021.

5. Big Data

Companies are looking for new ways to expand that are both smarter and more efficient. The Java programming language has a number of applications in the gathering, distribution, and analysis of large amounts of data.  Data administration in industries and associations becomes simple using Java. Smart predictions may also help an organization's predictive analytics, resulting in better strategies and growth. Java and robotics aren't mutually exclusive, but they do complement each other. If your company hasn't yet automated its core processes, you may be using time and money in the wrong direction, and you might face stiff competition.  Robotization becomes more efficient and pleasant using the Java support system. Needless to say, robotization will dominate the industry in near future, and Java software development services will be a significant part of it.

6. Remote Access

The Coronavirus pandemic forced most of the working population to work from home, and now it has become the new normal. Many businesses, particularly those in IT, have made remote work an official location.  Since Java is a language used by professionals who work on the Internet, the development and supply of remote solutions will become the next trend. The domains created in recent years include video calls, remote work apps, management solutions, and so on.  All of this becomes a lot more pleasant and convenient to build with Java. It is necessary to make sure that both the server and the client-end things run well. This necessitates a thorough understanding of Java.

7. Cloud-Based Models

Java developers will focus their high-end efforts on cloud computing in 2021 and the future. The popularity of Java app development services is likely to rise as more businesses and organizations turn to cloud technologies to manage their data.  Because of its stability, simplicity of use, and security, Java is one of the finest programming languages for cloud computing. Java-based cloud computing apps can operate on a variety of operating systems, including iOS, Windows, and others.

8. SaaS & PaaS

Software as a Service (SaaS) and Platform as a Service (PaaS) has a solid market position and are likely to continue to expand in the future. However, PaaS is expected to surpass SaaS due to an increase in demand by remote workers for high-performance infrastructure which will enable them to work from home effectively.  Since Java is appropriate for this, anyone who wants to develop a PaaS application can get it done with the help of a Java web application development company.

9. Regular Updates

One of the other important aspects of Java is the six-month release cycle of its new versions, which basically implies that there will be more regular updates and a speedier introduction of functionality to Java programs. All of these functionalities allow Java to be used to solve new problems and explore new fields. Java 8 was the most popular version among developers even before the release of Java SE 16 in March 2021. Since public upgrades for private and commercial usage were accessible, many IT specialists devoted themselves to Java 8. Although there were no more commercial or public usage upgrades as of December 2020, the version was still significant because of the long-term maintenance feature. JDK 16 has 17 new features including language enhancement, improved memory management, a new packaging tool, UNIX-domain socket channels, etc. JDK 17 is scheduled to be released in September 2021.
