The abstract superclass for this inheritance hierarchy has been renamed MyMoving-
Shape. Add a public method named moveShape to the class. It should take no arguments and have no return type. Two new instance variables, dx and dy, have been added to the MyMovingShape class for you. Variable dx holds the distance along the x-axis that the shape must travel in one move. Variable dy holds the distance along the y-axis that the shape must travel in one move. Add dx to the x1 and x2 values and add dy to the y1 and y2 values. Follow good programming practice by using the cor- responding get and set methods instead of modifying the variables directly.
