Some Java Predictions in 2019

1
DISCLAIMER This is simply a prediction by the
author, No authenticated statements or roadmaps
from by us and anyone else.
2
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.
3
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
  cant 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.
4
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.
5
OpenJDK became a market leader for Java Runtime

• Many Professional Java Developers miss the fact
  that oracle's its 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.
6
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.
7
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.
8
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.
9
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.
