Then set JAVA HOME on your Mac as shown below:
Shell

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home

Then, run below command to check your JAVA HOME.

Open a new terminal window.
Open a .profile file by typing: emacs .profile
Type below commands:
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home
export JAVA_HOME;
Then, do the (ctrl-x, ctrl-s; ctrl-x, ctrl-c) to save and exit emacs.
Open a new terminal and run below command:
$JAVA_HOME/bin/java -version
You should see below screenshot with your java version number.
