Subclass Constructors. This constructor explicitly initializes the cx and cy fields newly defined by PlaneCircle , but it relies on the superclass Circle() constructor to initialize the inherited fields of the class. To invoke the superclass constructor, our constructor calls super(). super is a reserved word in Java.
