I would recommend learning java away from the i... get setup on windows and
go through various tutorials, learn how install, how to debug, run code etc
you can use RDI for that or use eclipse just to get up and running

Once you are comfortable running tutorials on windows, learn how to move
that code over to the i, and then run it there... theres a learning curve
as theres a few things to setup differently, but its not huge....

if you know sql, its a big advantage as the basics really dont change much
from system to system...
if you want to go hard core, the next step is to learn how to call java
stored procedures in the db, and also calling java from rpg...

the big thing with java is not the language itself, as that relatively
straightforward for the basic stuff.... but learning the concepts of oop
and some of the more recent language elements such as lambda expressions,
functional interfaces and streams can be a bit intense... and the big thing
is learning a lot of the libraries and frameworks that are available for
java... as java has been around for a long time there are many... getting
familiar with those makes a huge difference but will take time...

have fun!

I began looking at visualAge but it appears it is no longer supported and
was wondering if RDI is an adequate IDE for java on the 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.
