A function for switching between Java JDKs on OS X

setjdk.sh

# I'm in a situation where I have multiple JDKs installed for various projects.  While I'm sure there are a million was to handle this
# issue (a number of sites recommended jenv), I just wanted a quick & easy way to switch between JDKs that are installed on my machine.
# I took the following steps:
#
# 1.  Add the functions below to your ~/.bash_profile
# 2.  Source your ~/.bash_profile (command is . ~/.bash_profile) or exit and reload your terminal window
#
# These functions came from here:  https://www.jayway.com/2014/01/15/how-to-switch-jdk-version-on-mac-os-x-maverick/, so all credit goes to the author of that article
