Installed JDK, but terminal still doesn't recognize java -version?
After following the video and downloading the JDK, everything went successfully except for when I attempted to verify the installation by typing java -version into the terminal. The terminal still didn't recognize the command, and outputted: "-bash: java: command not found." Any help would be much appreciated. Thanks.

It sounds like the PATH environment variable does not include the location of the java runtime. If you're still in the same terminal window as you used for the install, try opening a new one and see if it works there. If it does, just close the old terminal.
If it still doesn't, then the install didn't update the run command file to extend the PATH, possibly because the installation didn't have the proper privileges. In that case you might try reinstalling as "root".
