ASSIGNMENT $3$

Assignment $3$ tests your basic knowledge of Arrays and ArrayList $($Chapter $7),$ Text Processing and wrapper classes $($Chapter $8),$ and classes and

inheritance $($Chapter $9)$ and should have the following exact $($name$,$ parameters, types, and functionality$)$ classes, fields, and methods, order, and

have your name in the names $($replace YourName with your actual name$)$ and exact requested functionality.

$1.$ Design an abstract class called YourNamePet with the following exact fields, methods, and functionality, in this order:

Field$/$Method Description

name A private string field that holds the name of the pet $($e$.$g$.$ Spot, Fluffy$)$

type A private string field that holds the type of animal that the pet is $($e$.$g$.$ dog, cat, bird, fish, rabbit$)$

YourNamePet A constructor with $2$ parameters name and type that initializes the $2$ fields with the corresponding parameters$$ values.

sound An abstract void method that output the sound the pet makes.

eat A void method that outputs $$Eating$...$

sleep A void method that outputs $$Sleeping$...$

toString A string method that returns a string with the format: $$NAME$=$name, TYPE$=$type$$ where name and type are the fields$$ values.

$2.$ Design a class called YourNameCat that extends the YourNamePet class with the following exact fields and methods:

Field$/$Method Description

YourNameCat A constructor with one parameter name that calls the superclass constructor to set the superclass name field to parameter

name and type to $$cat$.$

sound Override the superclass method to output $$Meow$$

purr A void method that outputs $$Purring$...$

jump A void method that outputs $$Jumping$...$

toString Override the superclass toString method to add $$CAT: $$ at the beginning.

$3.$ Design a class called YourNameDog that extends the YourNamePet class with the following exact fields and methods:

Field$/$Method Description

YourNameDog A constructor with one parameter name that uses the superclass constructor to set the superclass field name to parameter

name and the type to $$dog$.$

sound Override the superclass method to output $$Woof$$

fetch A void method that outputs $$Fetching$...$

run A void method that outputs $$Running$...$

toString Override the superclass toString method to add $$DOG: $$ at the beginning.

$4.$ Design a class called YourNameData with the following exact fields and methods:

Field$/$Method Description

cats A private array or ArrayList of YourNameCat objects field that holds the cats

dogs A private array or ArrayList of YourNameDog objects field that holds the dogs

YourNameData A no$-$arg constructor that reads the data from the Assingment$3$Data.txt files The format of the file lines is $$name type$$ with

the $2$ one$-$word values separated by a tab. Then, if the type is $$cat$,$ create an object of type YourNameCat and add it to the

cats array and if it is $$dog$,$ create an object of type YourNameDog and add it to the dogs array.

printCounts A void method that computes the numbers of cats and dogs from the class and print the NumberCats and NumberDogs in this

format: $$CATS$=$NumberCats, DOGS$=$NumberDogs$.$

printCats A void method that looks at each object from the cats arrays, and uses the toString of the object to get the string format and

print it$,$ and calls the eat, sleep, sound, purr, jump, to demonstrate the other object methods.

printDogs A void method that looks at each object from the dogs arrays, and use the toString of the object to get the string format and

print it$,$ and call the eat, sleep, sound, fetch, run to demonstrate the other object methods.

$5.$ Design a driver class called YourNameAssignment$3($replace YourName with your actual name$)$ with this main functionality:

$$ Creates an object of the YourNameData class called myData.

$$ Use myData object$$s printCounts method to print the numbers in the specific format

$$ Use myData object$$s printCats to print the cats data.

$$ Use myData object$$s printDogs to print the dogs data.

$6.$ Implement the classes in NetBeans IDE and JAVA: Create a JAVA project called YourNameAssignment$3($same name as the driver class$),$ add the

class YourNamePet, YourNameCat, YourNameDog, YourNameData to the YourNameAssignment$3$ project and add your code to the YourNamePet,

YourNameCat, YourNameDog, YourNameData classes and YourNameAssignmen$3$ project$/$driver class main method. Your program should be welldocumented$/$commented $($have comments for every line of code$)$ and use only concepts learned in class $($chapters $19).$

$7.$ Create the screenshot document for your code and output: Create a Microsoft Word document from the YourName$-$Assignment$3.$docx template

and call it YourName$-$Assignment$3.$docx $($replace YourName with your actual name$)$ with your screenshots of the NetBeans editor window showing

the entire JAVA source code for the $5$ YourNameAssignment$3,$ YourNamePet, YourNameCat, YourNameDog, and YourNameData classes and the

entire output. If the entire class JAVA source code or the output does not fit in one screenshot or the screenshots cannot be easily read, c
