This is the most clear video on How to install JAVA in Mac I have ever found in internet :)

Thank you so much, I was on Java 6 and I was not sure why I couldn’t do certain things but when I found out I didn’t know how to fix it but this video helped a ton and everything works now thanks man.

Hi Raghav, can you please update your video at 5'31'' and just add a note saying that you actually need to type "source .bash_profile" and THEN "echo $JAVA_HOME" in order to display the path ? Thanks Sai Niranjan for your comment.

hi, I had a question pls. I try to switch my java version from 1.7 to 1.8 in terminal. when I test it by java -version or Java - version, i's 1.8 and exactly all good. but, if I quit current terminal and reopen it to check the version, it will come back to 1.7.🤔 probably need to save, but not sure how to do this pls.
