FRC Java Beginner - Help

[TeamMarcies]

Hello,

I am in charge of programming for my team along with a few others and we all know Java to a great extent. More specifically, we've been doing Java for 2-3 years so we know it to the intermediate extent, enough to program a robot of-course.

Last year (Grade 10 for me), we were using Labview and we were met with many setbacks and limitations that were absolutely annoying and we wish to transition our focuses to Java as it will be much more flexible to handle rather than the one-way Labview.

I, personally am planning to get started in learning the Java FRC API (WPI) during the summer so I can easily get a hand of things when the next competition hits.

Question(s):

1. What is the best area to get started in learning the Java FRC API?
Prefer: Videos & PDF

2. Now for my second question - Is there some sort of a plugin or robot emulator in which I can test my FRC Java code with as you obviously can't run the Java code and truly test if the robot is doing what you need it to do without the chassi, etc.

3. Finally, I would love it if someone can give me an eBook / Video(s) explaining how the FRC Robot works like terminology and how it ties in with the programming so I will be able to program the robot understanding what everything means...

Thanks in advance.
