1. Code is in Java. Will leave thumbs up and Thank you! To start, create a package hw2 for the
assignment under your project for ITEC 2150. Part 1 Create a Part 1 subpackage p1 under the
hw2 package. In the p1 subpackage, create a public abstract class Shape3D that models three-
dimensional shapes. Create the following data fields and methods in the class: - A protected data
field color which is of type String and a getter for the field. - A constructor public Shape(String
color) that sets the color field to the argument. - Public abstract methods volume() and
surfaceArea() with no argument that return the volume and surface area of the shape,
respectively. The return type of both methods should be double. Create a public (concrete) class
Ball as a subclass of the Shape3D class, and the following data fields and methods in the Ball
class: - A private data field radius of type double representing the radius of a ball. - A constructor
public Ball (String color, double radius) that sets the color and radius fields to the corresponding
arguments. - Public (concrete) methods volume() and surfaceArea() that override and implement
the corresponding abstract methods of the Shape3D class. They should compute and return the
volume and surface area of the ball, respectively. Of a ball with radius r, the volume is 34r3 and
the surface area is 4r2 - A toString method that returns a string in the default format of Intellij.
Create a public (concrete) class Box as a subclass of the Shape3D class, and the following data
fields and methods in the Box class: - Private data fields length, width and height of type double
representing the length, width and height of a box, respectively. - A constructor public Rectangle
(String color, double length, double width, double height) that sets the color, length, width and
height fields to the corresponding arguments. - Public (concrete) methods volume() and
surfaceArea() that override and implement the corresponding abstract methods of the Shape3D
class. They should compute and return the volume and surface area of the box, respectively. Of a
box with length l, width w and height h, the volume is lwh and the surface area is 2(lw+lh+wh) -
A toString method that returns a string in the default format of Intellij. Create a public (concrete)
class Cylinder as a subclass of the Shape3D class, and the following data fields and methods in
the Cylinder class: - Private data fields radius and height representing the radius of the base
circle and the height of a cylinder, respectively. - A constructor public Cylinder (String color,
double radius, double height) that sets the color, radius and height fields to the corresponding
arguments. - Public (concrete) methods volume() and surfaceArea() that override and implement
the corresponding abstract methods of the Shape3D class. They should compute and return the
volume and surface area of the cylinder, respectively. Of a cylinder with radius r and height h,
the volume is r2h and the surface area is 2rh+2r2 - A toString method that returns a string in the
default format of Intellij.

2. Create a public class named Shape3dTest. In the main method of the class: - Create an Array List
of Shape3D objects. - Create a Random object using 2150 as the seed. - Create one Ball object
with each of the three colors red, green and blue in this order, using a random integer between 1
and 20 as the radius. Add the three Ball objects in this order to the shapes list. - Create one Box
object with each of the three colors red, green and blue in this order, using a random integer
between 1 and 50 as the length, a random integer between 1 and 20 as the width, and random
integer between 1 and 60 as the height. Add the three Box objects in this order to the shapes list.
- Create one Cylinder object with each of the three colors red, green and blue in this order, using
a random integer between 1 and 15 as the radius and a random integer between 1 and 50 as the
height. Add the three Cylinder objects in this order to the shapes list. - Write a loop to print, in
separate lines, each element of the shapes list as well as its volume and surface area.
