Problem Description

Hello! Please make sure to read all parts of this document carefully.

In this assignment, you will be applying your knowledge of abstract classes, inheritance, polymorphism, file I$/$O and exceptions. For this homework, you will be simulating a veterinary clinic. You will create a Pet.java, Dog.java, Cat.java, InvalidPetException.java, and a Clinic.java file; the Clinic.java file will treat and keep a record of the Pet patients it receives!

Solution Description

Create files Pet.java, Dog.java, Cat.java, InvalidPetException.java and Clinic.java. Each file will have instance fields, methods, and constructors.

Pet.java

This class represents any pet that would seek consultation from the clinic.

Variables:

String name

double health

A percentage value ranging from $0\mathrm{.}0$ to $1\mathrm{.}0$

int painLevel

Ranges from $1$ to $10$

Constructor:

Pet$($String name, double health, int painLevel$)$

health

If health passed in is greater than $1\mathrm{.}0,$ set health to $1\mathrm{.}0$

If health passed in is less than $0\mathrm{.}0,$ set health to $0\mathrm{.}0$

painLevel

If painLevel passed in is greater than $10,$ set pain level to $10$

If painLevel passed in is less than $1,$ set pain level to $1$

Methods:

getters for all instance fields, which should be camelCase with the variable name, e$.$g$.$ a variable named hello should have a getter getHello$()$

int treat$()$:

Should be an abstract method that returns the time taken $($in minutes$)$ to treat the pet

void speak$()$:

This method prints $$Hello$!$ My name is $$ with the pet$$s name

If painLevel is greater than $5$ prints the message in UPPERCASE

boolean equals$($Object o$)$:

Two Pet objects are equal if their names are the same

Note: You can assume you will not encounter two pets with the same name

heal$()$:

Should be protected to prevent access by external classes

Sets health to $1\mathrm{.}0$

Sets painLevel to $1$

Dog.java

Since a Dog is also a Pet, this class must inherit from parent class Pet. This class is concrete.

Variables:

double droolRate

Constructors:

Dog$($String name, double health, int painLevel, double droolRate$)$

droolRate $-$ If droolRate is less than or equal to zero, set drool rate to $0\mathrm{.}5$

Dog$($String name, double health, int painLevel$)$

Default droolRate is $5\mathrm{.}0$

Methods:

getters for all instance fields, which should be camelCase with the variable name, e$.$g$.$ a variable named hello should have a getter getHello$()$

int treat$()$:

Should heal$()$

Returns the time taken $($in minutes$)$ to treat the pet. Round values up$.$

if droolRate is less than $3\mathrm{.}5,$ the minutes for treatment is $($painLevel$*2)/$health

if droolRate is in between $3\mathrm{.}5$ and $7\mathrm{.}5$ inclusive, the minutes for treatment is painLevel$/$health

if droolRate is greater than $7\mathrm{.}5,$ the minutes for treatment is painLevel$/($health$*2)$

void speak$()$:

Calls parent method

Prints $$bark$$ number of times of the painLevel

e$.$g$.$: if painLevel $=3$

Prints $$bark bark bark$$

ALL UPPERCASE if painLevel is greater than $5,$ not inclusive

boolean equals$($Object o$)$:

Uses the equals$()$ method in Pet as part of the decision$-$making with the additional condition of droolRate being the same

Cat.java

Since a Cat is also a Pet, this class must inherit from parent class Pet. This class is concrete.

Variables:

int miceCaught

Constructors:

Cat$($String name, double health, int painLevel, int miceCaught$)$

miceCaught

If miceCaught passed in is less than $0,$ set miceCaught to $0$

Cat$($String name, double health, int painLevel$)$

Default miceCaught is $0$

Methods:

getters for all instance fields, which should be camelCase with the variable name, e$.$g$.$ a variable named hello should have a getter getHello$()$

int treat$()$:

Should heal$()$

Returns the time taken $($in minutes$)$ to treat the pet. Round all values up$.$

if number of miceCaught is less than $4,$ the minutes for treatment is equal to $($painLevel $*2)/$health

if miceCaught is in between $4$ and $7$ inclusive the minutes for treatment equals painLevel$/$health

if miceCaught is greater than $7,$ the minutes for treatment equals painLevel$/($health$*2)$

void speak$()$:

Calls parent method

Prints $$meow$$ number of times of miceCaught

Eg: if miceCaught $=3$

Print $$meow meow meow$$

ALL UPPERCASE if painLevel is greater than $5,$ not inclusive

boolean equals$($Object o$)$:

Uses the equals$()$ method in Pet as part of the decision$-$making with the additional condition of miceCaught being the same

InvalidPetException.java

An unchecked exception with two constructors

Constructors

InvalidPetException$()$ has message $$Your pet is invalid!$$

InvalidPetException$($String s$)$ has message s

Clinic.java

This is a class representing the vet clinic.

Variables

File patientFile

File with patient information

int day

Constructors

Clinic$($File file$)$

File that contains patient info $-$ assign to patientFile

Name

Type of pet $($includes pet info$)$

Appointment Info

timeIn$($military time$)$

health$($before Treatment$)$

painLevel$($before Treatment$)$

TimeOut$($military time$)$

TimeOut$($military time$)$

Day initialized to $1$

Clinic$($String fileName$)$

String include
