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:

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" 

The following license changes are necessary to proceed:
 (see "package.license" in the portage(5) man page for more details)
# required by oracle-jdk-bin (argument)
>=dev-java/oracle-jdk-bin-1.8.0.11 Oracle-BCLA-JavaS


To accept the required license, create the directory /etc/portage/package.license if it does not already exist.

# mkdir /etc/portage/package.license


After we create this directory, portage will read files that we create inside of it to see that we have accepted licenses required to install certain packages. To accept the license for oracle-jdk-bin, create a file called something like /etc/portage/package.license/oracle-jdk-bin and add the line dev-java/oracle-jdk-bin Oracle-BCLA-JavaS to it:

# tee /etc/portage/package.license/oracle-jdk-bin <<< "dev-java/oracle-jdk-bin Oracle-BCLA-JavaS"


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
