Java Beginner Tutorial 3 - How to install or update JAVA on Mac

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.

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.

Use "source ~/.bash_profile" to run the script only then Java home will display output

@Automation Step by Step hello sir, I have MacBook Air m1, how do I install jdk file on this.
please help me on this.

Thanks for the detailed video, Ragahv. Just wanted to inform many people with updated macOs might be facing issue where echo $JAVA_HOME command will not show the path set. For those just wanted to mention, for me my terminal default was Z shell or zsh. People can find it looking at the top bar of the terminal. For you it is bash, so the echo command display JAVA_HOME. For people Facing this issue, use " source ~/.bash_profile command " after setup and closing the window. Also see below to change terminal

Edit:
If you want to change your terminal, you can use the following commands on any opened terminal window

For bash:
chsh -s /bin/bash

For Zsh:
chsh - s /bin/zsh

Excellent Raghav Sir Salute to you for making thing so simple

Hello! Trying to use your appium tutorial so installing Java for that. I have followed how to do the ./bash part but can't get it to work. I have an updated version so I am trying to set this
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home once I go back and run echo $JAVA_HOME I just get a blank

Thank you for the tutorial.

It looks like i have 3 Virtual Machines :(

Matching Java Virtual Machines (3):
10.0.2 (x86_64) "Oracle Corporation" - "Java SE 10.0.2" /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home
1.8.291.10 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
1.8.0_291 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home


I would like to remove "Java", the middle one. How do i do that?

if i set in export JAVA_HOME=$(/usr/libexec/java_home -v 1.8) in .bash_profile

then java -version is showing

java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)

and javac -version is showing

javac 10.0.2

How to make both java and javac version same?
Please help.

I have performed , vi ~/.bash_profile , Then press i for insert mode and then typed export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-15.0.2.jdk/Contents/Home and the press esc and typed :wq! and enter

But when I am performing vi ~/.bash_profile it is now showing me "export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-15.0.2.jdk/Contents/Home" . But why vi ~/.bash_profile is blank which means my env variables arent setting up. pls help
