Answer:
Following are the code in java language
abstract interface PointingDevice // interface PointingDevice,
{
// abstract method getXCoord()
public abstract int getXCoord();
// abstract method getYCoord()
public abstract int getYCoord();
// abstract method attentionRequired()
public abstract boolean attentionRequired();
// abstract method setResolution( )
public abstract double setResolution(double a);
}
Explanation:
In this code we have declared a abstract interface "PointingDevice" which contains the four abstract method getXCoord of type int , getYCoord() of type int , attentionRequired() of type boolean and setResolution() of type double .
These method have only declaration not definition any interface or class which inherit the inteface PointingDevice must define all these four method otherwise it also be abstract .
