Java installation¶

For Linux derivatives¶

Ubuntu¶

Tip

On Ubuntu, you can either choose the default OpenJdk or install the official Oracle JDK (through an additional software repository). Note that Oracle change its business policy recently (jdk not free anymore)

OpenJdk¶

OpenJdk versions 7, 8 and 11 can be installed through the official repos starting Ubuntu trusty and are maintained by Canonical.

$ sudo apt-get install openjdk-11-jdk

To set the system wide default jdk, simply launch the update-alternatives command :

$ sudo update-alternatives --config java

Oracle JDK¶

Deprecated install notes

The Oracle JDK is available through an external ppa repository.

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer

To set the system wide default jdk, simply install the oracle-javaX-set-default package, where X stands for the version you need.

$ sudo apt-get install oracle-java8-set-default

Redhat / Centos¶

On Redhat systems,

OpenJdk¶

OpenJdk versions 6 and 7 can be installed through the official redhat repos

$ yum install java-1.7.0-openjdk-devel

Oracle JDK¶

For Redhat subscribed users, you can refer to this solution.
