Class Diagram:
In Assignment #5, you will need to make use of inheritance by creating a class hierarchy for summer
camps.
Assignment 5: CSE 205: Object-Oriented Program & Data
SummerCamp is an abstract class, which represents the basic attributes of any summer camp. It is used
as the root of the summer camp hierarchy. It has the following attributes (should be protected):
Attribute name Attribute type Description
title String A title for a summer camp
location String A location for a summer camp
weeklyRate double some weekly Rate for a summer camp
numberOfWeeks int A number of weeks for a summer camp
totalCost double some total cost to be computed for a summer camp
The following constructor method should be provided to initialize the instance variables. Please refer to
the UML class diagram for their parameter types, and return type.
public SummerCamp(iString someTitle, String someLocation,
double someWeeklyRate, int someNumberOfWeeks)
The instance variables title, location, weeklyRate, and numberOfWeeks are initialized to the value of the
first parameter, the second parameter, the third parameter, and the forth parameter
respectively. totalCost should be initialized to 0.0.
The following mutator method should be provided for instance variable the camp title
String getCampTitle( )
The SummerCamp also has an abstract methods (which should be implemented by its child classes:
void computeTotalCosts( )
The following toString method should be provided:
public String toString()
toString method returns a string of the following format:
\nCamp Title:\t\tRobotics4\n
Location:\t\tCoor172\n
Weekly Rate:\t\t$70.00\n
Weeks:\t\t\t3\n

https://canvas.asu.edu/courses/44324/pages/assignment-5?module_item_id=2823054 4/11
Total Cost:\t\t$0.00\n
You should make use of the NumberFormat class (in java.text package) to format the weekly rate and
total cost. NumberFormat should be used with an object of Locale (in java.util.Locale, i.e.,
Locale usMoney = new Locale(“en”, “US”); ) by specifying to use the US currency.
DebateCamp class
DebateCamp is a subclass of SummerCamp class. It has the following attribute in addition to the
inherited ones:
Attribute name Attribute type Description
materialFee double some material fee for the debate camp
groupDiscount boolean where it has a group discount or not
The following constructor method should be provided:
public DebateCamp (String title, String location, double rate, int weeks, double materialFee,
String discount)
The constructor of the parent class should be called using the first, second, third, forth, and fifth
parameters to initialize its title, location, weeklyRate, numberOfWeeks, materialFee. If the parameter
discount is yes, the instance variable groupDiscount should be set to true, and if it is
no, groupDiscount should be set to false.
The following methods should be implemented:
public void computeTotalCosts( )
This method should update its totalCost as follows. Its basic total cost is computed
as weeklyRate * numberOfWeeks. If groupDiscount is true, then it should get a 10% discount,
i.e., weeklyRate * numberOfWeeks should be multiplied by (0.9). Then its materialFee should be added
to it.
Also, the following method should be implemented:
public String toString()
The toString() method inherited from SummerCamp class should be used to create a new string, and
display a savings account’s information using the following format (note that if groupDiscount is true, it
should show yes for Group Discount and it should show no otherwise):
\nDebate Camp:
\nCamp Title:\t\tDebateLevel5\n

https://canvas.asu.edu/courses/44324/pages/assignment-5?module_item_id=2823054 5/11
Location:\t\tPSH153\n
Weekly Rate:\t\t$45.25\n
Weeks:\t\t\t4\n
Total Cost:\t\t$0.00\n
Material Fee:\t\t$12.00\n
Group Discount:\t\tyes\n\n
This toString method should make use of the toString method of its parent class.
You should make use of the NumberFormat class (in java.text package) to format the weekly rate, total
cost, and material fee. NumberFormat should be used with an object of Locale (in java.util.Locale, i.e.,
Locale usMoney = new Locale(“en”, “US”); ) by specifying to use the US currency.
RoboticsCamp class
RoboticsCamp is a subclass of SummerCamp class. It has the following attribute in addition to the
inherited ones:
Attribute name Attribute type Description
facilityFee double some facility fee for the robotics camp
competitionFee double some competition fee for the robotics camp
The following constructor method should be provided:
public RoboticsCamp(String title, String location, double rate, int weeks, double facilityFee,
double compFee)
The constructor of the parent class should be called using the first, second, third, forth, fifth, and sixth
parameters to initialize its title, location, weeklyRate, numberOfWeeks, facilityFee competitionFee.
The following methods should be implemented:
public void computeTotalCost( )
This method should update its totalCost as follows. Its basic total cost is computed
as weeklyRate * numberOfWeeks. Then itsfacilityFee and competitionFee should be added to it.
Also, the following method should be implemented:
public String toString()
1/28/2020 Assignment 5: CSE 205: Object-Oriented Program & Data (2020 Spring)
https://canvas.asu.edu/courses/44324/pages/assignment-5?module_item_id=2823054 6/11
The toString() method inherited from SummerCamp class should be used to create a new string, and
display a savings account’s information using the following format:
\nRobotics Camp:
\nCamp Title:\t\tRobotics4\n
Location:\t\tCoor172\n
Weekly Rate:\t\t$70.00\n
Weeks:\t\t\t3\n
Total Cost:\t\t$0.00\n
Facility Fee:\t\t$37.50\n
Competition Fee:\t$17.50\n\n
This toString method should make use of the toString method of the parent class.
You should make use of the NumberFormat class (in java.text package) to format the weekly rate, total
cost, facility fee, and competition fee. NumberFormat should be used with an object of Locale
(in java.util.Locale, i.e., Locale usMoney = new Locale(“en”, “US”); ) by specifying to use the US
currency.
MathCamp class
MathCamp is a subclass of SummerCamp class. It has the following attribute in addition to the inherited
ones:
Attribute name Attribute type Description
testTaking boolean whether taking a test or not
The following constructor method should be provided:
public MathCamp(String title, String location, double rate, int weeks, String testTaking)
The constructor of the parent class should be called using the first, second, third, and forth parameters to
initialize its title, location, weeklyRate, numberOfWeeks. If the parameter testTaking is yes, the instance
variable testTaking should be set to true, and if it is no, testTaking should be set to false.
The following methods should be implemented:
public void computeTotalCosts( )
This method should update its totalCost as follows. Its basic total cost is computed
as weeklyRate * numberOfWeeks. If testTaking is true, $25 should be added to it.
1/28/2020 Assignment 5: CSE 205: Object-Oriented Program & Data (2020 Spring)
https://canvas.asu.edu/courses/44324/pages/assignment-5?module_item_id=2823054 7/11
Also, the following method should be implemented:
public String toString()
The toString() method inherited from SummerCamp class should be used to create a new string, and
display a savings account’s information using the following format (note that if testTaking is true, it should
show yes for Test Taking Discount and it should show no otherwise.):
\nMath Camp:
\nCamp Title:\t\tAlgebra1\n
Location:\t\tCoor120\n
Weekly Rate:\t\t$65.75\n
Weeks:\t\t\t4\n
Total Cost:\t\t$0.00\n
Test Taking:\t\tyes\n\n
This toString method should make use of the toString method of the parent class.
You should make use of the NumberFormat class (in java.text package) to format the weekly rate and
total cost. NumberFormat should be used with an object of Locale (in java.util.Locale, i.e.,
Locale usMoney = new Locale(“en”, “US”); ) by specifying to use the US currency.
SummerCampParser class
The SummerCampParser class is a utility class that will be used to create an object of a child class
of SummerCamp class from a parsable string. The SummerCampParser class object will never be
instantiated. It must have the following method:
public static SummerCamp parseStringToSummerCamp(String lineToParse)
The parseStringToSummerCamp method’s argument will be a string in the following format:
For a debate camp with its type “DebateCamp”
type:title:location:weeklyRate:numberOfWeeks:materialFee:groupDiscount
For a robotics camp with its type “RoboticsCamp”
type:title:location:weeklyRate:numberOfWeeks:facilityFee:competitionFee
A real example of this string would be:
DebateCamp:Intro:WGHL101:30.50:6:9.50:no
OR
1/28/2020 Assignment 5: CSE 205: Object-Oriented Program & Data (2020 Spring)
https://canvas.asu.edu/courses/44324/pages/assignment-5?module_item_id=2823054 8/11
RoboticsCamp:Robotics4:Coor172:70.0:3:37.50:17.50
OR
MathCamp:Algebra1:COOR120:65.75:4:yes
This method will parse this string, pull out the information, create a new object of its corresponding child
class of the SummerCamp class with attributes of the object, and return it to the calling method. The type
will always be present and always be either DebateCamp, RoboticsCamp, or MathCamp. (It can be lower
case or upper case) You may add other methods to the child classes in order to make your life easier.
