If you have more javas and you want to switch between the javas, you can select a java from the javas with this...
function jhome | |
set -x JAVA_HOME (/usr/libexec/java_home $argv) | |
echo "JAVA_HOME:" $JAVA_HOME | |
echo "java -version:" | |
java -version | |
end |

This little ditty uses sets the java_home based on /usr/libexec/java_home to the local shell.
Usage:
set JAVA_HOME to latest java
set JAVA_HOME to a certain java version
