Adapted from College Board Unit $9\mathrm{.}6,$ FRQ#$1$ 'Pet'

Burkham, $2024$

PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA.

Assume that the classes listed in the Java Quick Reference have been

imported where appropriate.

Unless otherwise noted in the question, assume that parameters in method calls

are not null and that methods are called only when their preconditions are satisfied.

In writing solutions for each question, you may use any of the accessible methods

that are listed in classes defined in that question. Writing significant amounts of

code that can be replaced by a call to one of these methods will not receive full credit.

The Pet class is used to represent pets and print information about each pet.

Each Pet object has attributes for the pet name and species.

The Dog class is a subclass of the Pet class that has one additional attribute:

a String variable named breed that is used to represent the breed of the dog.

The Dog class also contains a printPetInfo method to print the name and breed of the dog.

CONDITIONS:

$-$ Up to $5$ Java statements $($total for all $3$ parts$)$ may be added

$-$ Other lines of code may not be changed

$-$ Your final implementation should conform to the 'FINAL OUTPUT' example $($at end$)$

$-$ Format, line spacing, etc. must match exactly

NOTES:

Properly use at least one method super.

Do not use any getter method!!

Use a comment for each line.

PART A:

Consider the following code segment.

Pet pet$1=$ new Pet$("$Floppy$",$ "rabbit"$)$;

Pet pet$2=$ new Pet$("$Arty$",$ "dog"$)$;

pet$1.$printPetInfo$()$;

pet$2.$printPetInfo$()$;

The code segment is intended to print the following output.

Floppy is a rabbit

Arty is a dog

Complete the Pet method printPetInfo$().$

PART B:

Consider the following code segment.

Dog fluffy $=$ new Dog$("$Fluffy$",$ "pomeranian"$)$;

fluffy.printPetInfo$()$;

The code segment is intended to print the following output.

Fluffy is a dog of breed pomeranian

Complete the Dog method printPetInfo$().$

PART C:

The PetOwner class below is used to generate a description about a pet and its owner.

The PetOwner constructor takes a Pet object and a String value $($representing the name

of the pet owner$)$ as parameters.

Code Segment Result Printed

owner$1.$printOwnerInfo$()$; Floppy is a rabbit owned by Jerry

owner$2.$printOwnerInfo$()$; Arty is a dog of breed pug owned by Kris

Complete the PetOwner method printOwnerInfo$().$

FINAL OUTPUT:

The final formatted output $($all $3$ parts completed$)$ should be exactly this:

Floppy is a rabbit

Arty is a dog

Fluffy is a dog of breed pomeranian

Floppy is a rabbit owned by Jerry

Arty is a dog owned by Kris
