Write an interface, PointingDevice, containing:
an abstract method, getXCoord that returns an int
an abstract method, getYCoord that returns an int
an abstract method, attentionRequired that returns a boolean
an abstract method, setResolution that accepts a double and returns a double.
//My code
public interface PointingDevice {
int getXCoord();
int getYCoord();
boolean attentionRequired();
double setResolution(double a);
}
