I am trying to add methods to help with reading our robots actual speed off of a CANJaguar in fps. The issue I am having now is that it is not building becasue it needs a constructor, but if I am inheriting the class shouldn't they already exist. What i want to be able to do is when i call a CANJaguar object, e.g. leftMotor.getFps(), it will return the fps data to me. This is my code so far.

Any help is greatly appreciated.

public class fps extends CANJaguar {

    final static double PI = Math.PI;
    private double WheelSize;
     /**
     * Get the speed of your robot.
     *
     * @return The speed of the robot in fps.
     */
    public double getFps() throws CANTimeoutException {
        byte[] dataBuffer = new byte[8];
        byte dataSize;
        double rpms;

        dataSize = getTransaction(JaguarCANProtocol.LM_API_STATUS_SPD, dataBuffer);
        if (dataSize == 4) {
            rpms = unpackFXP16_16(dataBuffer);
        } else {
            rpms = 0.0;
        }
        
        double fps = 0;
        fps = (rpms *(WheelSize * PI))/(60 * 12);
        return fps;
    }
    
    public void setWheelSize(double WheelSizeInInches) {
        WheelSize = WheelSizeInInches;
        }
}

and this is my current compiler output
