Homework SourseNeed help writing java program that follows Write an inherit
Need help writing java program that follows:
Write an inheritance hierarchy for class Quadrilateral, Trapezoid, Parallelogram, Rectangle, and Square. Use Quadrilateral as the super class of the hierarchy. Make the hierarchy as deep I.e., as many levels) as possible. Specify the instance variables and methods for each class. The private data of the Quadrilateral should be the x-y coordinate pairs for the four end-points of the Quadrilateral. Write a program that instantiate objects of you classes and outputs each object area (except Quadrilateral)
desired output should look something like this :
Coordinates of Quadrilateral are:
(1.1, 1.2) , (6.6, 2.8), (6.2, 9.9), (2.2, 7.4)
Coordinates of Trapezoid are:
(0.0,0.0) , (10.0, 0.0), (8.0, 5.0), (3.3, 5.0)
Height is : 5
Area is : 36.75
Coordinates of Parallelogram are:
(5.0,5.0) , (11.0, 5.0), (12.0, 20.0), (6.0, 20.0)
Width is: 6
Height is : 15
Area is : 90
Coordinates of Rectangle are:
(17.0,14.0) , (30.0, 14.0), (30.0, 28.0), (17.0, 28.0)
Width is: 13
Height is : 14
Area is : 182
Coordinates of Square are:
(4.0, 0.0), (8.0,0.0), (8.0, 4.0), (4.0, 4.0)
Side is: 4
Area is: 16
