Stay up to date with JDK 14 news

Java 14: Five more JEPs target JDK 14 & Project Amber update

Java 14, the third version since the last LTS release, is in development. Java 12 and Java 13 each came with a manageable number of new features; a system that will probably not change for Java 14. This is of course due to the new release cadence. What’s new is that five JEPs were upgraded from “proposed” to “targeted” for JDK 14, and we’ve seen some stirrings from Project Amber.

Just the algorithm, not the GCs themselves

JEP 366: Deprecate the ParallelScavenge + SerialOld GC Combination

We’ve seen a lot of talk about different garbage collectors lately; JEPs 364 and 365 want to port the Z Garbage Collector to macOS and Windows respectively, JEP 363 wants to remove the deprecated Concurrent Mark Sweep (CMS) garbage collector. And now we have JEP 366, which is proposed to target JDK 14 and wants to deprecate the combination of the Parallel Scavenge and Serial Old garbage collection algorithms. Let’s take a closer look.

Sweet 6.0

Gradle 6.0 brings Java 13 support, better dependency management & much more

It’s not even been a year since Gradle 5.1 arrived in January, and yet here we are staring down the next major release: Gradle 6.0. This latest release of the build-automation software brings much improved features for dependency management, faster incremental compilation for Java and Groovy, support for Java 13, as well as out of the box support for javadoc and source jars. And that’s not all, so let’s take a closer look!

Something something Windows garbage

JEP 365: ZGC on Windows

The Z Garbage Collector or ZGC is a scalable low latency garbage collector that’s included in the JDK. Until now, it has not been compatible with Windows, but JEP 365 wants to change that. Let’s take a closer look at the future of Java.

JEP 364: ZGC on macOS

The Z Garbage Collector or ZGC is a scalable low latency garbage collector that’s included in the JDK. Until now, it has not been compatible with macOS, but JEP 364 wants to change that. Let’s take a closer look.

Why value types are important

The new ValueType in Java

Java, as it is now, has two different types of data—primitives and objects. In the coming releases, there will be a new type that is called ValueType. For everyday programming, there should be no difference between objects and value types but under the hood they are really different. They are like objects but work as if they were primitives. The second part of the sentence means: they are effective. Other languages have this type of data handling, though they usually do not call them with this name.

Déjà preview

JEP 368: Text Blocks (Second Preview)

Remember text blocks? That’s right, they were a preview feature in the recently released Java 13! Now that some time has passed, the community has a feel for them and where there’s room for improvement. With JEP 368, Jim Laskey proposes a second text blocks preview, this time with two more escape sequences. Let’s take a closer look.

Taking out the trash

JEP 363: Remove the Concurrent Mark Sweep (CMS) Garbage Collector

A new Java enhancement proposal, JEP 363, has graduated from being a simple draft. It proposes to remove the Concurrent Mark Sweep garbage collector, which was deprecated two years ago to accelerate the development of other collectors. Let’s take a closer look at the future of Java.

TIOBE Index for November 2019

Top programming languages for November 2019: C gets an A+

Every month, we keep tabs on the TIOBE Index to see which programming languages are rising up the charts. The November 2019 update sees a few changes, including a slight rise for C and Python. TIOBE predicts that it is possible for C to overtake Java and become number 1 again by the end of the year. Meanwhile, what is Dice saying about the top paid programming languages?
