iFour Technolab has hosted a meetup titled “JAVA 8 TO 19 - NOW AND THE FUTURE” on 3rd September 2022 which covered the core concepts of Java. The session was fully focused on the introduction of Java features from version 8 to version 19 and how they eased and aided the development process.

Java now and the future

Mr. Dhaval Desai, our Java team head, and team members Yash Shukla, and Mohammad Awais Memon led this session. The main goal of arranging this meetup was to educate and inform employees about the newly introduced features of Java, how they reduced lines of code, and how to utilize them syntactically to save time.

The meetup began with an overview of Java and how it differs from other platforms in terms of its environment.

Java now and the future

Mr. Dhaval Desai says - “This general-purpose programming language is highly preferred by E-commerce, and financial sectors due to its unbreakable security. Java had its version releases on regular basis; however, the versions were divided into two categories: "Long-term support (LTS)" and "basic support." Since the introduction of this policy, Java 7, 8, 11, and 17 have been recognized as LTS versions.”

Java now and the future

One of the experts described the global statistics of Java and why it is the preferred choice of various tech giants.

Yash Shukla says - “According to statistics, 69% of experts choose Java 8, while 36% prefer Java 11, making them the most popular Java versions for software development. Hence keeping up with LTS versions is essential.

Oracle stated that future LTS versions would henceforth be released every two years. This means Java 21, the next LTS version, will be ready in September 2023.”

Java now and the future

The Java community strives to include features that not only save developers' time but also minimize source code in order to improve application performance. They work on specific projects to test new feature enhancements. Some of the major ongoing projects include –

  • Project Loom

  • Project Panama

  • Project Valhalla

  • Project Amber

Mohammad Awais, an accomplished Java developer at iFour, described each of these ongoing projects as well as the types of enhancements that each project is working on in detail.

Java now and the future

More than 60 experts attended this two-hour meetup, where they passionately exchanged technical experiences, and offered their perspectives on software development using Java.

To demystify various versions of Java, one of our specialists presented the list of versions from V8 to V19, along with the kind of features available in each.

As discussing each feature in detail would take a long time, the team had decided to pick the most crucial features in each version and described them practically.

Java now and the future

To make this session more exciting, our Java team leader went back to basics, discussed queries, and provided a few intriguing examples to illustrate the distinctions between conventional and updated syntaxes.

Here is a glimpse of features we discussed in the session –

  • Encapsulation

  • Java 9 – Private methods in Interface

  • Java 10 – Local Variable Type Inference

  • Java 14 – Switch Expressions (Standard)

  • Java 16 – Pattern Matching for instanceof

  • POJO Class vs Record Class

  • Java 17 – Pattern Matching for Switch (Preview)

  • Guards and Dominance

  • Java 17 – Sealed Classes

Employees’ participation in this meetup was tremendous which was evidenced by many insightful questions. This bolstered the team’s confidence.

While Awais explained the POJO and Record classes, Yash Shukla, a Java enthusiast at iFour, added more clarity on OOPs fundamentals by highlighting the differences between strongly typed and loosely typed languages. To make things more interesting, he explored -

  • the use of Switch statement

  • how to use Arrow syntax in Switch

  • Case Null clause in Switch

  • using Switch as an expression

Mr. Dhaval Desai concluded this 2-hour Java meetup by saying - “We are immensely delighted to host this meetup. I’d like to thank everyone and express my gratitude to the Java team for their outstanding efforts in making this session a success. Wishing you all the best. Looking forward to your unwavering commitment towards Learning and Development. Thank you!”
