THIS CODE BELOW IS THE WORKING POINT, RECTANGLE, AND BOX CLASS REQUIRED TO BE ABLE TO ANSWER THIS QUESTION:

class Point { // instance variables private int x; private int y; private int z;

// default constructor to set (x,y,z) to (3,4,5) public Point() { setX(3); setY(4); setZ(5); }

// parameterized constructor to set (x,y,z) to specified values public Point(int x, int y, int z) { setX(x); setY(y); setZ(z); }

// setters // method to set the value of x public void setX(int x) { this.x = x; }

// method to set the value of y public void setY(int y) { this.y = y; }

// method to set the value of z public void setZ(int z) { this.z = z; }

// getters // method to return the value of x public int getX() { return x; }

// method to return the value of y public int geY() { return y; }

// method to return the value of z public int getZ() { return z; }

// method to return String representation of Point object public String toString() { return "("+x+", "+y+", "+z+")"; } }

Instructions: Make sure that you follow the Program Style and Readability guidelines found in the Start Here Folder. NOTE: YOU NEED YOUR POINT, RECTANGLE, AND BOX CLASS FOR THIS ASSIGNMENT 1. Start with a working Point class. Refer to the Point program created for Lab #1 a. Make Point an abstract class b. Add an abstract method called calcArea c. 2. Write a new Circle class, a subclass of the Rectangle class. a. Add a radius variable to the new class. b. Add constructors i. a default Circle where: 1. call super constructor with a width of 6. length of 0, and height of 6, color is cyan 2. radius = 3 ii. a 1 argument constructor Circle(radius) 1. call super with a width of 2 times radius, length of 0. height of 2 times radius and a color of yellow. c. Override the calcArea method i. Calculates the area of a Circle object: area= 3.14 * radius * radius ii. returns the area of a Circle object 111. Do not store the area in a member instance) variable. d. Override the toString method to display (and label) all of the characteristics (instance variables) of a Circle object. Do not forget to include the super instance variables by using the super.toString(. Do not include area in the toString output...only instance varliables are part of the toString Lab 3 - Advanced Java Inheritance, Polymorphism, abstract Types 3. Write a new Cylinder class, a subclass of the Circle class. a. Add length as a new variable b. Add 1 constructor: Cylinder(int radius int length. Color color) i. Call the super sending the radius, length and color ii. Initial length c. Add get() and set () methods as needed. d. Override the area method inherited from the Circle class to calculate the outside face area of a Cylinder object i. Calculates: area= 2 * 3.14 * radius * radius + 2 * 3.14 * radius * length ii. returns the area of a Cylinder object 111. Do not store the area in a member variable. e. Add a method called volume that: i. Calculates the volume of a Cylinder object: volume = 3.14 * radius * radius * length. ii. returns the volume of a Cylinder object 111. Do not store the volume in a member variable. f. Override the toString method inherited from class Circle class to display (and label) all of the characteristics (instance variables) of a Cylinder object. Once again, use the super.toStringO. 4. Write an executable client class called ShapesAbstractTester - a separate program - that uses the Point, Rectangle, Box, Circle, Cylinder classes. a. Create an array of the Point class Point[] myShapes = new Point[4]: b. Populate the array with a new Rectangle(6,9, 0, blue) in myShapes[0]; C. Populate the array with a new Circle(12) in myShapes[1]; d. Populate the array with a new Box(25, 15, 20, pink) in myShapes[2]; e. Populate the array with a new Cylinder(5, 36, lightgray) in myShapes[3]; f. Using a for loop examine each item in the array with the instanceOf method to determine if the object is a cylinder, circle, box, or rectangle. i Print out the type of object and the object's toStringo ii. Only "type an object once iii. If an object is a cylinder then do not call it a circle as well iv. If an object is a box then do not call it a rectangle as well v. Print the area for all objects vi. Print the volume for box and cylinder vii. NOTE: You must use a for loop and the instanceof method to recieve full credit for this lab.
