What error do you get? Which `.profile` are you trying to edit, the one associated with your user `/Users/${username}/.profile`, right? – Alexandru Somai Apr 08 '20 at 14:53

@AlexSomai one in /etc. Edited the question. there's no .profile in /Users/${username}/ – Divya Barsode Apr 08 '20 at 14:56

You can create it if there isn't any `.profile` file. – Alexandru Somai Apr 08 '20 at 15:10

Try to edit the .profile from your user, and not the one under /etc (to edit that one you need sudo rights, and even if you do edit it, most probably it won't be read correctly).
So, as a regular user (not sudo), open the one from your user. Using open (as in your screenshot, but I would rather choose vim). One of the below commands should work:
open ~/.profile
or
open /Users/${your-username}/.profile
I guess ${your-username} is divya, so the complete path would be:
open /Users/divya/.profile
If you get an error saying The File /.../.profile does not exist, first create an empty one:
touch ~./profile
Add in the .profile file, the following line:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
(make sure to use the Java version installed on your machine)
Then, for the changes to take place, either restart your terminal window, or type:
source ~/.profile
And to validate that you've set the $JAVA_HOME correctly:
echo $JAVA_HOME
Followed by:
java -version

Also one more doubt. I have been confused quite a lot. the path for java_home would it be 'export JAVA_HOME=`/Library/Java/JavaVirtualMachines/jdk-1.8.0_241.jdk/Contents/Home`' since the Home folder has bin? – Divya Barsode Apr 08 '20 at 15:16

It says permission denied for the given java path when I do 'source ~/.profile' – Divya Barsode Apr 08 '20 at 15:25

Hey, can you suggest to me about this last doubt? It will be a lifesaver for me. No more doubt after this I promise – Divya Barsode Apr 08 '20 at 15:42

Hmm ... this is new to me, as well. Try to close and re-open the terminal, and check if it outputs the `$JAVA_HOME` like that. – Alexandru Somai Apr 08 '20 at 15:46

I found this https://stackoverflow.com/questions/26686084/linux-java-in-path-but-permissions-denied .. but the last command did not work for chown stating such a group 'root' does not exist. – Divya Barsode Apr 08 '20 at 15:50

You can try just `sudo chown -R root`, without the `:group`. But I'm not sure if that will solve your problem. – Alexandru Somai Apr 08 '20 at 15:52

Just tried again what I've posted in my answer, and it works in my case, no errors on the `source` command :/ – Alexandru Somai Apr 08 '20 at 15:55

And this is the JAVA_HOME I've set `export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home` – Alexandru Somai Apr 08 '20 at 15:55
-
:/ il give it a try again or search some more. Thank you so much for your help :) – Divya Barsode Apr 08 '20 at 15:59

Ok it worked. i had written JAVA_HOME=`'/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home'`. I removed those quotes (the one with ~) and it worked. – Divya Barsode Apr 08 '20 at 16:01

Cool :) I'll update my answer to include that, for future readers. – Alexandru Somai Apr 08 '20 at 16:02
