Installing Java 10 on Linux

I’ve put together how to install Java 10 on Linux. It installs just fine on both Ubuntu and Linux Mint. I referred to the linuxuprising documentation.

1. Preparing the Installation

I’m not sure why, but as of April 15, 2018, Java 10 isn’t available through apt-get. By the time you’re reading this, it might be available, so let’s check.

sudo apt-cache search java10

If it’s not in apt-get yet, let’s install it from the PPA repository. I also tried the approach of downloading the JDK tar file and manually configuring PATH and JAVA_HOME, but for some reason it didn’t work on Linux Mint.

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update

2. Installation

Now let’s install Oracle Java 10.

sudo apt install oracle-java10-installer

Don’t be alarmed by the blue screen—you need to agree to the license for the installation to proceed. The installation takes quite a while.

On Ubuntu, Oracle Java 10 is automatically set as the default, but on other distributions such as Linux Mint, you have to set it yourself.

sudo apt install oracle-java10-set-default

And with that, the installation is complete.

3. Verification

Let’s verify that the installation went well.

java -version

If Oracle Java 10 was correctly installed as the default, you’ll see a message like the following.

java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+46)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+46, mixed mode)

Let’s check javac as well.

javac -version

If the installation went well, you’ll see this message.

javac 10

Now let’s start using Java 10!
