Hi Experts,
I'm fairly new to PI and so far I haven't had to program any UDFs in Java yet, but I feel it is only a matter of time before my lack of knowledge will catch up to me. They no longer seem to be offering JA100 - SAP J2SE Fundamentals course in English from what I've been told. I would appreciate any advice on how best to learn Java programming (for what is needed in PI) and whether something is offered through SAP, externally, free online, etc.
Thanks,
Matt

It really is more scripting than "real" Java programming, so I don't think a formal course is necessarily required.

Hi Matthew!
In addition to Patrick's answer, I would recommend to spend some time for reading good books, for example, "Thinking in Java", for better understanding java essentials. Java development in PI is not limited by writting UDFs only.

learn about java oops concepts and API.
in pi also whether it is UDF or java mapping or adapter module, you have to use sap's java api.
by googling you can find many tutorials and forums.
https://javaranch.com/ is very friendly place where you can ask any silly questions. No matter how silly it is still they will help you.
