rectangle class contains tge following;
-three data fields name recname, height and width with default values"Ricky" for recName, 5 for the height and 15 for the width.
-default constructor with no arguments
-constructor that accept width and height to create a rectangle
-the accessor of all data feilds
-methods that returns the area of the rectangle called getArea()
-methods that returns the perimeter of thr rectangle called getPerimeter()
-methods that returns the spring description of the rectangle called toString()
Note: the toString() method is implemented as follows :
Return " Rectangle : height = " + height + " width = " + width "

Design a general class GeometricObject can be used to model all geometric objects. This class contains the properties color and filled and their appropriate get and set methods. Assume that this class also contains toString() methods. The toString() method returns a string representation of the object. Define the Triangle, Circle, and Rectangle classes that extend the GeometricObject class. The Triangle class inherits all accessible data fields and methods from the GeometricObject class.In addition, it has three double data fields named...
JAVA design a class named Rectangle to represent a rectangle. The class contains: A method named getPerimeter() that returns the perimeter. Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. A no-arg constructor that creates a default rectangle. A constructor that creates a rectangle with the specified width and height. A method named getArea() that returns the area of this rectangle. design...
