Sample State Diagram and Corresponding Code Generated?

Hi to everyone in the forums, I’m new here… and I’m trying the software right now…
My major interest is to know how a simple state diagram translate to java code…
I wanted to know if there is some simple sample state diagram I can use to generate the code for.
I looked for it over the site and I found nothing.

I don’t if I can even ask for things here, sorry for the inconvenience and thank you for your time.
