2019 - Some Predictions of Java

DISCLAIMER: This is simply a prediction by the author, No authenticated statements or roadmaps from by us and anyone else.

JAVA 11 BEGINS TO LOOK SMALL BUT IS QUITE ACCEPTABLE This may be the least controversial prediction in the list.

Virtually no deployment is seen in Java 9 and 10 productions. Many teams are waiting to release the post-8 LTS, and now it is here, a small but stable Java 11 will start to be accepted. The greenfield deployment of brand-new applications will be an obvious place for teams to start accepting Java 11.

Prediction: Java 11 is approximately 10% of the entire Java product installation in late 2019.

NO BIG-TO-LARGE PORTING OF CURRENT APPS FROM 8 TO 11 So far, the Java upgraded path for apps was fairly clean. Between 6 to 7 or 7 to 8, in almost all cases, it was completely painless. The same can’t be said for upgrades from 8 to 11 - important tasks are usually required to move non-trivial applications to a newer version.

Prediction: No specific quantifiable prediction.

PYTHON 2 / PYTHON 3 DOES NOT HAVE ANY ANALOGY With the advent of modular Java, a lot has been said about the possibility that ecosystem python 2 / python 3 split will be experienced by the community as well. Python syntax and key data types make changes between versions, so the library and app writers should consciously choose which language version is being targeted and this choice will be based on a per-project basis for the full ecosystem.

Aired.

Prediction: No specific quantifiable prediction.

OPENJDK BECAME A MARKET LEADER FOR JAVA RUNTIME Many Professional Java Developers miss the fact that oracle's it’s offering is only for paying customers, so in the future java 8 (and 11, once java 12 is released) will be the only free-in-in-beer support offering from non-oracle organizations, adopt OpenJDK project, powered by community such as red hat, Amazon, Azul systems and multi-dealer, community.

The good news is that there is a drop-in replacement for OpenJDK oracle JDK, for server-side applications (and faster for desktop java applications).

Prediction: At the end of 2019, more than 50% of Java 8 and Java 11 production runtime Oracle is using OpenJDK than JDK.

THE RELEASE OF JAVA 12 Java12 is a feature-frozen and is expected to release in march 2019. Excepting a big event, it is difficult to see that it does not go on time.

Prediction: Java 12 is released over time and delivers rounding-error product at the end of 2019.

THE RELEASE OF JAVA 13 Java is yet to release on September 13, 2019. Details of any features currently available on this release are not available.

Like Java 12, it's a feature release, not its release.

Accordingly, at this time for some reason, suppose it will not go away in time. With the same way, the teams focus on Java rather than rotate 11 production centers, are not likely to see widespread acceptance.

Prediction: Java 13 is released over time and delivers rounding-error product at the end of 2019.

THE INITIAL VERSION OF MATCH EQUATIONS AS A PREVIEW IN JAVA 13 Switch expression is prerequisite for match expressions. Without expressing the expression in syntax, it is impossible to organize match expressions within the Java language. Indeed, without match expressions, there is very little issue in introducing switching expressions.

Prediction: Initial, limited form of match expression is included as a preview feature in Java 13.

MINOR GROWTH OF KOTLIN The Kotlin language of JetBrains has attracted the growing interest from developers in recent years. Especially, in the android space, the explosion and Kotlin have been dominated by new projects on android.

However, in server-java java, there is no comparable explosion in the traditional heartland for JVM languages.

In the year 2019, I see Kotlin gradually adopting, but there are no upcoming projects/teams. There will be many high-profile projects that will be used publicly to use Kotlin.

Prediction: Initial, limited form of match expression is included as a preview feature in Java 13.
