Source code for "Database Tools and SQL Support in IntelliJ IDEA"

So I came across this video of IntelliJ IDEA:

It helped me to import my settings to IntelliJ.

However, as I am a newbie in Java, and I really want to test-run the program, can anyone give the the source code of the Customer class.

Thanks in advance.
