Answer 1

1) Open Project Structure present under File menu or use shortcut ctrl+alt+shift+S

2) SDKs is located under Platform Settings. Select it and click the green + up the top of the window.

3) Set JDK home directory path (e.g.: /usr/lib/jvm/java-1.8.0-openjdk-amd64) and click on Apply and OK.

You should be able to execute your program now.

Answer 2

open File -> Project Structure, under project SDK, where it says no JDK select dropdown and check if they are any JDKs available, select available JDK then click Apply then OK, your project should run now.
