Encoders and gyro - no idea

[joelg236]

Programming in java, absolutely no idea whats wrong but both the gyro and the encoders attached to the motors give no output.
the encoders are attached to channels 1,2,3,4 (I didnt wire, and dont know how to) in slot 2. The gyro is in slot 1 on channel 1. We have inputed these values into our code but still no real input. Gyro gives a float point that means nothing (Still a number but not useful) and the encoders simply give us 0. Thought I'd ask you good people for some advice since we have no idea. (No experience with FRC, I'm good with Java)

Thanks in advance
