Define a class named

Circle

that is derived from this API superclass:

java.awt .geom.Ellipse2D.Double

See Exercise 6 for a brief description of this

Double

superclass. Your subclass should declare the two

private

instance variables,

xCtr

and

yCtr,

initialized to 0.0. These variables are the x- and y-coordinates of the circle’s center. Your class should include a zero-parameter constructor, and it should also include a three-parameter constructor whose parameters are the x- and y-distances to the circle’s center and the circle’s diameter. This three-parameter constructor should not only initialize the new instance variables but also use the four-parameter constructor of the superclass to initialize the four instance variables in the superclass. Your class should also provide the following accessor methods:

getXCtr, getYCtr,

and

getRadius,

where the radius is half the height of the superclass shape. Verify the code you write by compiling it and running it with representative values for x-center, y-center, and diameter.
