You can install the free icedtea jdk or Oracle's version. Therefore we have a virtual package called virtual/jdk. By default it will install the Oracle version. Jdk is Java SE Runtime Environment (JRE) & additional software for development.

Installation

# emerge -a virtual/jdk


If you receive a message similar to the following, you will have to accept the Oracle java license to emerge the oracle-jdk-bin:

# emerge virtual/jdk
Calculating dependencies... done!
[ebuild  N     ] dev-java/java-config-wrapper-0.16 
[ebuild  N     ] sys-apps/baselayout-java-0.1.0 
[ebuild  N     ] app-admin/eselect-java-0.1.0 
[ebuild  N     ] dev-java/java-config-2.2.0-r1000   PYTHON_ABIS="2.7 3.3 -2.6 -3.1 -3.2 -3.4 (-3.5)" 
[ebuild  N     ] dev-java/oracle-jdk-bin-1.8.0.11  USE="X alsa fontconfig nsplugin (-aqua) -derby -doc -examples -jce -pax_kernel (-selinux) -source"


Now you can emerge oracle-jdk-bin

# emerge virtual/jdk


After the installation finishes, you may want to check and see if you can use the jdk. You can do so by issuing the following command:

$ java
