Description

This assignment is an opportunity to work with objects using inheritance and polymorphism. Write a program that creates one superclass $($parent$),$ several subclasses $($child$),$ and use polymorphism. Write code to create the following class hierarchy in your program.

$$Animal

$$

$$Bear Elephant$$ Monkey Sloth$$

Superclass

$$ Animal

Subclasses of Animal

$$ Bear

$$ Elephant

$$ Monkey

$$ Sloth

The code will perform actions on these objects and display information proving you have properly used inheritance and polymorphism. Use the provided file Animals.txt to test your code.

Specifications

Read these specifications to get an overview of assignment. When writing code, first create the classes.

$1.$ Add this assignment to your project called CS$1150$

$2.$ Create a Java class within that project called LastNameFirstNameAssignment$12$

$3.$ Follow $"$CS$1150$ Programming Assignments Policy"

$4.$ Create $1$ superclass Animal $($see Classes section below for details$)$

$5.$ Create $4$ subclasses: Bear, Elephant, Monkey, Sloth $($see Classes section below for details$)$

$6.$ Write a test program $($i$.$e$.,$ main$)$ that:

a$.$ Open the test file Animals.txt for reading.

b$.$ Creates a polymorphic array to store the animals.

i$.$ The $1$st value in the file indicates how big the array needs to be$.$

ii$.$ Be sure to use a regular array, NOT an array list.

c$.$ Uses a loop to fill the array with each animal$$s information read from a file.

i$.$ Instead of asking the user for information, you will read information from a file.

ii$.$ After reading the $1$st value $($array size$),$ read the remaining values to create the animal objects and place them into the array.

For each line in the file:

a$.$ Read the type $($bear$,$ elephant, etc.$),$ name, food, weight, sleep, and location of the animal.

b$.$ Create a specific animal object.

i$.$ The type indicates what object to create.

ii$.$ Note that type is not sent to the constructor, instead, it is only used in main.

c$.$ Place the animal object into the polymorphic Animal array.

iii. For help, see step $7$ below for details about the file and the Must Do and Tips.

$$

d$.$ AFTER all lines in the file have been read and all animal objects are in the array:

i$.$ Create a $2$nd loop to iterate through the array and:

$1.$ Display the animal$$s type $($Bear$,$ Elephant, etc.$)$

a$.$ Note that type is not an instance variable in Animal.

b$.$ Instead, we can use the instanceof operator to determine which object is in the current location in the array and display its type.

Animal$[0]$ is a Sloth

$2.$ Display name, weight, sleep, and location of animal

a$.$ Call toString to display these values.

$3.$ Call the following methods:

eat

sleep

swim

ii$.$ See output section at end of document for example output.

$7.$ Test file $($Animals$.$txt$)$ information:

a$.$ Run your code on the provided file Animals.txt to test your code.

b$.$ This is a test file, so DO NOT assume that your code should work for only $7$ animals in the order specified in the file.

c$.$ The file contains the following animals:

Animal

Name

Food

Weight

Sleep

Location

Sloth

Ace

Leaves

$12$

$15$

Urban Jungle

Bear

Po

Bamboo

$550$

$20$

Asian Passage

Monkey

Rafiki

Fruit

$27$

$17$

Lost Forest

Sloth

Sid

Leaves

$15$

$12$

Urban Jungle

Elephant

$12500$

$4$

Elephant Odyssey

Monkey

Louie

Fruit

$14$

$16$

Lost Forest

Bear

Baloo

Honey

$1050$

$18$

Asian Passage

d$.$ The $1$st line in the file is an integer value representing the number of animals in the file.

e$.$ The remaining lines contain details for each animal:

i$.$ There will be one animal for each line in the file.

ii$.$ The format of each animal line is as follows:

Type $($tells you what object to create $$ it is NOT stored as an instance variable in object$)$

Sloth Ace Leaves $1215$ Urban Jungle

Name Food Weight Sleep Location $($store these $5$ values in instance variables$)$

$$

f$.$ The Animal.txt file that is provided looks like this:

$7$Number of animals

Sloth Ace Leaves $1215$ Urban Jungle

Bear Po Bamboo $55020$ Asian Passage

Monkey Rafiki Fruit $2717$ Lost Forest$$Each line provides the

Sloth Sid Leaves $1512$ Urban Jungle$$details for one animal

Elephant Titan Grass $125004$ Elephant Odyssey$$

Monkey Louie Fruit $1416$ Lost Forest$$

Bear Baloo Honey $105018$ Asian Passage

Classes

Animal Class

$$ Description

o Class that represents an animal.

o Superclass in hierarchy.

$$ Private Data Fields $($all fields must be defined as private!$)$

o name $$ String

o food $-$ String

o weight $$ int

o sleep $-$ int

o location $-$ String

$$ Public Methods

o Constructor: public Animal$($String name, String food, int weight,

int sleep, String location$)$

$$ Creates an Animal by initializing all private data fields to incoming values.

o Getter for each instance variable $-$ name, food, weight, sleep, and location

o Setters $$ none $($this is being done on purpose so do NOT include setters$)$

o The following additional public methods. The only code in themethods is a statement that t
