Java IntelliJ Help

Hello, I have been following the android development path, I have made it to this point
https://www.codecademy.com/paths/introduction-to-android-with-java/tracks/introduction-to-android-and-java/modules/learn-java-hello-world/articles/what-is-an-ide

I have installed and followed the video provided on youtube letter for letter.
When I attempt to run the HelloWorld program inside of IntelliJ, the program will not appear for it to be selected. Please see the attached screenshot.

Any help is greatly appreciated!
