With the Oracle FMW 12c version release, one of the normal requirement is to switch between multiple jdk versions for 12c & 11g build environments in mac. Below is a simple script which can help you to do that:

function switchjdk() {  
  if [ -z $1 ]; then
 echo "please provide with the right jdk version to switch"
  else
 echo "switching to jdk version --- $1"
 export PATH=$(echo $PATH | sed -E -e "s;:$JAVA_HOME/bin?;;" -e "s;$JAVA_HOME/bin:?;;")
 export JAVA_HOME=$(/usr/libexec/java_home -v $1)
 export PATH=$JAVA_HOME/bin:$PATH
 echo $(java -version)
  fi  
 }  
switchjdk $1
