help with .java source in .pde file

in Programming Questions • 7 months ago

Sorry for the trivial question,

but I found this .java source code

How can I execute this source code starting from Processing?

I can copy the code inside a tab in the processing IDE and after?

Thanks for your help.

Simple copy / paste of the relevant parts, removing stuff not useful or blocking:
