Geometric Objects

1

Design a class named GeometricObject. This class contains:

color: color name of the object (default value: “white”)

filled: indicates if the object is filled with color or not (default value: false)

no argument constructor: create a GeometricObject with default values for arguments

argument constructor: create a GeometricObject with specified color and filled values

toString: method returns a string description of the object

Design a class named Triangle that inherits (extends) from GeometricObject. This class contains:

side1: first side of the triangle with default value 1.0

side2: second side of the triangle with default value 1.0

side3: third side of the triangle with default value 1.0

no argument constructor: creates a triangle with default values

constructor: creates a triangle with specified side1, side2, and side3 values

getArea(): a method that returns the area of the triangle

getPerimeter(): a method that returns the perimeter of the triangle

toString(): method returns a string description of the triangle object like that:

“Triangle: side1 = $side1, side2 = $side2, side3 = $side3”

Design a class named Rectangle that inherits (extends) from GeometricObject. This class contains:

height: the height of the rectangle with a default value 1.0

width: the width of the rectangle with a default value 1.0

no argument constructor: creates a rectangle with default values

constructor: creates a rectangle with specified width, height, color, and filled values

getArea(): a method that returns the area of the rectangle

getPerimeter(): a method that returns the perimeter of the rectangle

toString(): method returns a string description of the rectangle object like that:

“Rectangle: height = $height, width = $width”
