Help with Encoder

[4239 Mack]

We are using an encoder for the first time on our robot. Whenever we try to use it or declare it our robot doesnt work.

Encoder encoder = new Encoder(3, 4);

That is what we are using for the encoder and to get the values we are using.

encoder.get();

Can anyone help us set this up or provide a detailed tutorial for using an encoder in java?

EDIT: we have also tried using this.

Encoder encoder = new Encoder(3,4,false,EncodingType.k4x);
