5. Design a driver class called YourNameAssignment3 (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 YourNameAssignment3 (same name as the driver class), add the
class YourNamePet, YourNameCat, YourNameDog, YourNameData to the YourNameAssignment3 project and add your code to the YourNamePet,
YourNameCat, YourNameDog, YourNameData classes and YourNameAssignmen3 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 1 – 9).

ASSIGNMENT 3 WINTER
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.
name
type
YourNamePet
sound
eat
sleep
toString
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 Assingment3Data.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.
7. Create the screenshot document for your code and output: Create a Microsoft Word document from the YourName-Assignment3.docx template
and call it YourName-Assignment3.docx (replace YourName with your actual name) with your screenshots of the NetBeans editor window showing
the entire JAVA source code for the 5 YourNameAssignment3 , 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, create
multiple screenshots and add multiple screenshots to the screenshot document. Make sure both entire code and output is visible in the screenshots.
If your output is longer than a line and does not fit on one screen, Wrap Text in your output panel.
8. Submit your work: Submit YourName-Assignment3.docx on eCampus under the Assignment 3. Do not archive the files (e.g. no RAR, ZIP, etc.) or
submit other types/formats of files (e.g. no CLASS, PDF, JAVA, ZIP, RAR, etc.). Please take time after submitting to review the file and check it is correct
and resubmit it if there are any errors.
