MacOS Sierra installation JRE8, configuring environment variables

My MacOS Sierra version number 10.12.2, the JRE package installed is: JRE-8U112-MACOSX-X64.DMG

After you double-click Normal installation, entering java-version under terminal does not display the version properly, you need to configure environment variables.

Here's how:

Open Terminal, enter the following to create a profile in the current user directory:

VI ~/.bash_profile

Click the I key to enter edit mode, paste the following content:

Java_home= "/Library/Internet Plug-ins/javaappletplugin.plugin/contents/home"

Path= $JAVA _home/bin: $PATH

Classpath=.: $JAVA _home/lib

Export Java_home

Export CLASSPATH

Export PATH

Then click the ESC key, enter: Wq Save exit

Finally, run the command update under Terminal to make the configuration effective:

source. Bash_profile  

Enter java-version under Terminal to display the version successfully, if not, please log out.
