Java is about all I do now but I started with it in about 2001. The jump
from RPG III to Java was painful although I used the Java for RPG
Programmers book as a general guide. What I have found is that my Java
skills make picking up other languages much easier and I think it is the
OO orientation of the language. Most popular languages today have at
least an OO concept in mind, if not a full implementation. So, I count
my Java skills as a plus. It also made my transition to /FREE easier.

My Java development also made RDi a snap to get comfortable with because
I live in the Eclipse world most of the day (with long stretches in VS
Code as well). I am a seat of the pants programmer so I tend to graze
the Internet when I need some help. I don't learn well "online". I have
taken three instructor-led, in person, courses over the past many years
and they have been immensely helpful. IBM also has a great Java team
that can help when you flat out break something.
I am not sure how helpful an RPG to Java language side by side example
will help with learning curve. I had proposed a Java Introduction for
RPG programmers session at Common conferences before. I am not sure how
much interest there is from RPG'ers in jumping to Java or even learning
it. I love the language though. Most of my work is not console or UI
related. I write mostly Web Apps using Java Servlets (which run like a
champ on Tomcat on IBM i)

I best learn by example and comparing an rpgle pgm to a java pgm example
would be most appealing.
I appreciate any guidance you can provide.
