Oracle Announces Java 14! How to Install it on Ubuntu Linux
|
||
======
|
||
|
||
Recently, Oracle announced the general availability of Java 14 (or the Oracle JDK 14). If you are someone who wants to have the latest and greatest to experiment and develop stuff – you can try installing Java 14 on your Linux system.
|
||
|
||
Oracle JDK 14 (or simply Java 14) [release][1] includes a couple of new features if you’re interested to preview them. I’ve linked them below:
|
||
|
||
* [Pattern matching for instanceof][2]
|
||
* [Records][3]
|
||
* [Text Blocks][4]
|
||
|
||
|
||
|
||
In addition to the preview features, it packs in several improvements and additions. Quoting the press release, they mentioned the additional improvements as well:
|
||
|
||
> Additionally, the latest Java release adds Java language support for switch expressions, exposes new APIs for continuous monitoring of JDK Flight Recorder data, extends the availability of the low-latency Z Garbage Collector to macOS and Windows, and adds, in incubator modules, the packaging of self-contained Java applications and a new Foreign memory access API for safe, efficient access to memory outside of the Java heap.
|
||
|
||
Of course, if you want to dive into the exact details, you should check the [official announcement][1].
|
||
|
||
In this tutorial, I’ll show you the easy way to get Java 14 installed on your Ubuntu system. Read on.
|
||
|
||
**Note:** If you opt for Oracle Java 11 or above, you should learn about the new [Oracle Technology Network License Agreement][5] to know how it affects personal users, developers, and commercial organizations. Usually, these are free to use for development and testing – but not for production.

### How To Install Java 14 on Ubuntu Linux?
|
||
|
||
![][6]
|
||
|
||
For reference, I’ve successfully tried it on **Pop!_OS 19.10** where I had the **OpenJDK 11** installed as the default.
|
||
|
||
Here, we are going to use the Java 14 installer (originally based on WebUpd8 Java Package) by [Linux Uprising][7].
|
||
|
||
Simply enter the commands below in the terminal to get it installed:
|
||
|
||
```
|
||
sudo add-apt-repository ppa:linuxuprising/java
|
||
sudo apt update
|
||
sudo apt install oracle-java14-installer
|
||
```
|
||
|
||
This should do the job. And, when it’s done, if you want to make it the default, you can type in the following command to do it:
|
||
|
||
```
|
||
sudo apt install oracle-java14-set-default
|
||
```
|
||
|
||
It is worth noting that this is only for Ubuntu-based distributions. If you want to install it on Debian and other Linux distributions, you can follow [Linux Uprising’s detailed guide][7] on installing Java 14 as well.
|
||
|
||
### Wrapping Up
|
||
|
||
Of course, while this is about the bleeding edge features – if you do not want to break things, you might want to hold on to Java 11. If you want to experiment while knowing the risks, go ahead and give it a try!
