The assignment number, your name, StudentID, Lecture day/time, and a class description need to be included at the top of each file/class.
A description of each method is also needed. Some additional comments inside of methods (especially for a main method) to explain code that are hard to follow should be written.
New Skills to be Applied
In addition to what has been covered in previous assignments, the use of the following items, discussed in class, will probably be needed:
Inheritance
The protected modifier
The super Reference
Abstract class
NumberFormat/DecimalFormat ArrayList
Program Description Class Diagram:
In Assignment #5, you will need to make use of inheritance by creating a class hierarchy for summer camps.
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:
Camp Title:ttRobotics4
Location:ttCoor172
Weekly Rate:tt$70.00
Weeks:ttt3
Total Cost:tt$0.00
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 accounts information using the following format (note that if groupDiscount is true, it should show yes for Group Discount and it should show no otherwise):
Debate Camp:
Camp Title:ttDebateLevel5
Location:ttPSH153
Weekly Rate:tt$45.25
Weeks:ttt4
Total Cost:tt$0.00
Material Fee:tt$12.00
Group Discount:ttyes
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()
The toString() method inherited from SummerCamp class should be used to create a new string, and display a savings accounts information using the following format:
Robotics Camp:
Camp Title:ttRobotics4
Location:ttCoor172
Weekly Rate:tt$70.00
Weeks:ttt3
Total Cost:tt$0.00
Facility Fee:tt$37.50
Competition Fee:t$17.50
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.
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 accounts 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.):
Math Camp:
Camp Title:ttAlgebra1
Location:ttCoor120
Weekly Rate:tt$65.75
Weeks:ttt4
Total Cost:tt$0.00
Test Taking:ttyes
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 methods 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
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.
