For JDK 10

Option 1: Easy Installation (PPA)

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java10-installer

Then set as default with:

And finally verify Installation with: 

$ java -version
java version "10.0.1" 2018-04-17

Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

Source: Linux Uprising

Option 2: Manual Installation

  • Download OpenJDK 10 binaries for Linux.

  • Untar the downloaded archive:

    tar xzvf openjdk-10_linux-x64_bin.tar.gz

  • Move the extracted archive to where your system keeps your installed JDKs:

    sudo mv jdk-10 /usr/lib/jvm/java-10-openjdk-amd64/

  • Add the new Java alternative:

    sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-10-openjdk-amd64/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-10-openjdk-amd64/bin/javac 1

  • Update your system's java alternatives and choose JDK 10:

    $ sudo update-alternatives --config java
here are 3 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      auto mode
* 1            /usr/lib/jvm/java-10-openjdk-amd64/bin/java      1         manual mode
  2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
  3            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      manual mode

Press <enter> to keep the current choice[*], or type selection number:

    and

    $ sudo update-alternatives --config javac
There are 3 choices for the alternative javac (providing /usr/bin/javac).

  Selection    Path                                          Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-9-openjdk-amd64/bin/javac    1091      auto mode
  1            /usr/lib/jvm/java-10-openjdk-amd64/bin/javac   1         manual mode
  2            /usr/lib/jvm/java-8-openjdk-amd64/bin/javac    1081      manual mode
  3            /usr/lib/jvm/java-9-openjdk-amd64/bin/javac    1091      manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/lib/jvm/java-10-openjdk-amd64/bin/javac to provide /usr/bin/javac (javac) in manual mode

  • Verify your installation with:

    $ java --version
openjdk 10 2018-03-20
OpenJDK Runtime Environment 18.3 (build 10+46)
OpenJDK 64-Bit Server VM 18.3 (build 10+46, mixed mode)

    and

    $ javac --version
javac 10

  • Done

If you prefer Oracle's JDK, download it and follow the installation steps as shown above.


I've found SdkMan! a very useful tool because it provides a convenient way for managing your JDKs from the shell.

For example, once it is installed, you can:

Install a specific JDK version: sdk install java 10.0.2-open

Downloading: java 10.0.2-open

In progress...

#################                             12,3%

Use a specific JDK version: sdk use java 10.0.2-open

Using java version 10.0.2-open in this shell.

List available JDK: sdk list java
