# Java

Check if Java is already installed

\$ java -version


If you see an output like below then Java is already installed on your machine so skip the next step.

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)


If you don't see the output like above then you need to install Java on your system. Please download the OS X version from the Oracle website.

Check if Java is correctly installed by running the java -version command again.

Add JAVA_HOME to your environment variables by adding the line below to your env.sh.

export JAVA_HOME="/usr/libexec/java_home -v 1.8"


You should have JAVA working now. You can use Eclipse or IntelliJ as your Java IDE.
