Using an Analog Ultrasonic Sensor

[Maxchrist]

Hi, I have been trying to use a maxbotix ultrasonic sensor to get a distance using java. The sensor is on an analog channel so it seems that I cannot use the frc api for the ultrasonic sensor. I have the math worked out, and it prints a distance in inches, however the voltage on the sensor is not changing when I move the sensor, which means it is not sending out signals. How can you start the sensor and make it send out sonar signals? Or if I am not going about this the right way, is there a better way to do this? this is what I have so far:
