Programming for sonar with MaxRobotix Sensor

[bs7280]

Hi, we are trying to get a reading from our MaxRobotix Sensor that we have plugged into pin 1 of the Analog input. We are using java (NetBeans) for programming. Some of our code:

Declaring variable:
public static final Button ultrasonicSensor = new AnalogIOButton(1);

And inside out Autonomous section, we simply print out ultrasonicSensor.get();

It would be greatly appreciated if someone could help us get a reading from our sensor so that we can work with it
