Thank you for responding rfuentealba. Unfortunately, that didn't work for me. I got this back: Unable to find any JVMs matching version "1.8". But you rightly diagnosed the problem and gave me some ideas.

Though I had installed Java 8 before, typing "java -version" into the Terminal showed my system reckoned with Java 11. After checking possible other solutions and experimenting, the following worked for me:

1. Open the .bash_profile file (in TextEdit) on the mac.
For me, it seemed the file didn't exist based on what I got back on the Terminal. I'll come back to that later. 
2. Edit the .bash_profile file with the following line: export JAVA_HOME='/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home'
3. Save the edited .bash_profile file
4. Open a new terminal window (and type java -version) to check. And the following confirm the change:

java version "1.8.0_231"

Java(TM) SE Runtime Environment (build 1.8.0_231-b11)

Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

As previously noted, there was a problem bringing up the .bash_profile file. I did the following to solve it:  

1. Start up the Terminal.
2. Type "cd ~/" to go to the home folder.
3. Type "touch .bash_profile" to create new file.
4. Type "open -e .bash_profile" to open it in TextEdit.

I found a few lines there relating to python and anaconda, which suggested to me that the file existed somewhere before and I don't know why it was not coming up before.
