The document discusses the features and enhancements in JDK 12, including the introduction of switch expressions, microbenchmark suite improvements, and the JVM constants API. It also covers the support for AArch64 architecture and advancements in garbage collection algorithms. The document provides contact information for the corporate and development centers.

2. JDK 12 with it's feature
• Java latest features for programmers at a
quicker access. I’ve seen some of the
specifications or features that you can predict
to see in the next Java version 12 release in
current year.
• You can get the open JDK 12 advance control to
develop and try out these existing version.
Let’s talking latest features in Java 12.

You have a define any calendar
year and you want to use
switch statement to retune the
number of words in the
characters. There are simply
way to do this but we are
moving to use switch
statements to below example.

5. Microbenchmark Suite
• Most of the time, I think it’s been when there are no benchmarks including
few library.
• By influencing coverage we can lower risk of regressions going move, and by
embedded with OpenJDK with both authoring new ones and executing more
tests on more device, I believe we’ll see better outputs over time.
• One intent of this JOB is to generate it simpler for OpenJDK projects to write
new micro benchmarks when and where code is correctly being modified.
Which will help getting early catch on problems as latest Java features are
being built.

6. JVM Constants API
• Here specify a relative of value
based symbolic resource, a
special character define a
loadable content is purely
official form. It also easy to
integrate into a program or
module.
• Component use - core-
libs / java.lang.invoke

7. AArch64 Port
• AArch64/ARM 64 Port supports a
huge items of device form large
organization aarch64 Server Base
System Architecture (SBSA)
compliant device down to cheap
single board computers.
• We’re mainly targeted on Server,
latest IoT and other devices are
similar to other Fedora architecture
support.

8. CDS Archives
• A simple CDS was available with
Sun JVM since java intermediate
version was limited to system
classes and serial GC only.
• In, oracle latest JDK 12 this finally
become useful, with support of
other algorithm and application
classes.

9. Abortable G1 Mixed Collections
• G1 garbage management not
manually return Java load
memory to the operating system
when inactive.
• There are many strategies of
Garbage Collection some of
which is perfectly for a specific
use case. In this presentation, we
have explored some of the top
Garbage Collection algorithms.
