Description
Program Description
Class Diagram:
President Class
The President class implements the “Serializable” interface so that its object can be stored. (The
Serializable interface is defined in the “java.io” package.) It needs to define the following method:
public void copy(President other)
It needs to copy every member variable value from “other” parameter to their corresponding variable
of the object itself using “this” reference. For instance, if we have two objects of President, president1
and president2, then, executing the following statement:
president1.copy(president2)
should resulting to have the object president1 to have the same companyName, locationCity, and
locationState value as the ones for president2, but president1 and president2 should not become
aliases.
Club Class
The Club class implements the “Serializable” interface so that its object can be stored. (The
Serializable interface is defined in the “java.io” package.) It needs to define the following method:
public void copy(Club other)
It needs to copy every member variable value from “other” parameter to their corresponding variable
of the object itself using “this” reference.
ClubNameComparator Class
The ClubNameComparator class implements the “Comparator” interface (The Comparator
interface is in “java.util” package.). It needs to define the following method that was an inherited
abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Club first, Club second)
instead by making the class implements Comparator.
If the first argument object has its club name less than that of the second argument, an int less than
zero is returned. If the first argument object has its club name larger than that of the second
argument, an int greater than zero is returned. If their club names are same, then 0 should be
returned. Note that it should use String comparisons, such as using the compareTo method of the
String class.
MemberNumberComparator Class
The MemberNumberComparator class implements the “Comparator” interface (The Comparator
interface is in “java.util” package.). It needs to define the following method that was an inherited
abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Club first, Club second)
instead by making the class implements Comparator.
If the first argument object has its number of members less than that of the second argument, an int
less than zero is returned. If the first argument object has its number of members larger than that of
the second argument, an int greater than zero is returned. If their numbers of members are same,
then 0 should be returned.
CurrentPresidentComparator Class
The CurrentPresidentComparator class implements the “Comparator” interface (The Comparator
interface is in “java.util” package.). It needs to define the following method that was an inherited
abstract method from Comparator interface:
public int compare(Object first, Object second)
(Note that you can also define:
public int compare(Club first, Club second)
instead by making the class implements Comparator.
If the first argument object has its last name less than that of the second argument, an int less than
zero is returned. If the first argument object has its last name larger than that of the second
argument, an int greater than zero is returned. If their last names are same, then their first names
should be compared. (if the first argument object has its first name smaller (in alphabetical order —
compareTo method of the String class), then it should return a negative integer. If the first argument
object has its first name larger, then it should return a positive integer. If their last names and first
names are same, then 0 should be returned.
Sorts Class
The Sorts class is a utility class that will be used to sort a list of Club objects. Sorting algorithms are
described in the algorithm note posted under Notes section of the course web site. These algorithms
sort numbers stored in an array. It is your job to modify it to sort an array of objects.
The Sorts class object will never be instantiated. It must have the following methods:
public static void sort(Club[] clubList, int size, Comparator)
Your sort method utilizes the compare method of the parameter Comparator object to sort. You can
use one of Selection sort, Insertion Sort, MergeSort, or QuickSort. The parameter size specifies how
many first elements should be sorted. Note that not all elements in the array should be sorted, since
some of them will be null pointers.
ClubManagement Class
The ClubManagement class has a list of Club objects that can be organized at the club management
system. The club management system will be a fully encapsulated object. The ClubManagement
class implements the Serializable interface.
It has the following attributes:
CSE 205: Object-Oriented Program & Data
Attribute name Attribute type Description
clubList
an array of Club
objects
A list of Club objects in the
club management system
numberOfClubs int
the number of Club objects
created and stored in the
clubList
maxSize int
the maximum number of
Club objects that can be
stored in the clubList array.
It is also the size of the
clubList array.
The following public methods should be provided to interact with the club management system:
Method Description
ClubManagement(int
maximumsize)
A Constructor of the ClubManagement
class. Using the parameter value, it
should initialize the member variable
maxSize. Then it should instantiate an
array of Club objects using the
maxSize, and initialize each slot of the
array to null for every index. It should
also initialize the member variable
numberOfClubs to 0.
int clubExists(String
clubName, String university)
Search for a Club object by clubName
and its university, and return the index
of the object if found. Return -1 if not
found. The parameters are the club
name and the university of a Club
object.
int
currentPresidentExists(String
Search for a Club object in the club list
that have the same president’s first
name, last name, and academic level
CSE 205: Object-Oriented Program & Data
firstName, String lastName,
String academicLevel)
as the parameter values and return the
index of such object if found. Return -1
if not found.
boolean addClub(String
clubName, int
numberOfMembers, String
university, String firstName,
String lastName, String
academicLevel)
Add a Club object to the club list and
return true if such object was added
successfully. Return false if an object
with the same club name and
university already exists or
numberOfClubs is already same as
maxSize, i.e., the array is full (the new
object is not added).
boolean removeClub(String
clubName, String university)
Remove a Club object of the parameter
clubName and the university from the
club list. Return true if the object was
removed successfully. Return false if
the object with the given club name
and university does not exist.
void sortByClubNames()
Sort the list of Club objects by club
names. This method calls the sort
method defined in the Sorts class,
using the clubList, and its maxSize, an
object of ClubNameComparator class.
void sortByMemberNumbers()
Sort the list of Club objects by their
numbers of members. This method
calls the sort method defined in the
Sorts class, using the clubList, and its
maxSize, an object of
MemberNumberComparator class.
void
sortByCurrentPresidents()
Sort the list of Club objects by their
president information including its last
names and first names. This method
calls the sort method defined in the
Sorts class, using the clubList, and its
CSE 205: Object-Oriented Program & Data
maxSize, an object of
CurrentPresidentComparator class.
String listClubs()
List all Club objects in the club list. The
returned string is the concatenation of
each Club object information in the list
for the number of numberOfClubs (do
not use the size of the array here) Hint:
you can utilize Club’s toString method
to help you complete this method. If
there is no object in the list, This
method should return the string
containing “\nno club\n\n”.
void closeClubManagement()
Closes the club management system
by making the clubList empty. This can
be done by making every slot of the
clubList array to null, and also by
setting numberOfClubs to be 0.
No input/output should occur in the club management system. User interaction should be handled
only by the driver class (Assignment8 class).
You may add other methods to the class in order to make your life easier.
Assignment8 Class
All input and output should be handled in Assignment8 class. The main method should start by
displaying this updated menu in this exact format:

Write Text to File
Your program should display the following prompt:
Please enter a file name to write:\n
Read in the filename and create an appropriate object to get ready to read from the file. Then it
should display the following prompts:
Please enter a string to write in the file:\n
Read in the string that a user types, say “input”, then attach “\n” at the end of the string, and write it
to the file. (i.e. input+”\n” string will be written in the file.)
If the operation is successful, display the following:
FILENAME was written\n
Replace FILENAME with the actual name of the file.
Use try and catch statements to catch IOException. The file should be closed in a finally statement.
Read Text from File
Your program should display the following prompt:
Please enter a file name to read:\n
Read in the file name create appropriate objects to get ready to read from the file. If the operation is
successful, display the following (replace FILENAME with the actual name of the file):
CSE 205: Object-Oriented Program & Data
FILENAME was read\n
Then read only the first line in the file, and display:
The first line of the file is:\n
CONTENT\n
where CONTENT should be replaced by the actual first line in the file.
Your program should catch the exceptions if there are. (Use try and catch statement to catch,
FileNotFoundException, and the rest of IOException.)
If the file name cannot be found, display
FILENAME was not found\n
where FILENAME is replaced by the actual file name.
Serialize ClubManagement to File
Your program should display the following prompt:
Please enter a file name to write:\n
Read in the filename and write the serialized ClubManagement object (the variable clubManage1)
out to it. Note that any objects to be stored must implement Serializable interface. The
Serializable interface is defined in java.io.* package. If the operation is successful, display the
following:
FILENAME was written\n
Replace FILENAME with the actual name of the file.
Use try and catch statements to catch NotSerializableExeption and IOException.
Deserialize ClubManagement from File
Your program should display the following prompt:
Please enter a file name to read:\n
Read in the file name and attempt to load the ClubManagement object from that file. Note that there
is only one ClubManagement object (the variable clubManage1) in the Assignment8 class, and the
first object read from the file should be assigned to the ClubManagement object. If the operation is
successful, display the following (replace FILENAME with the actual name of the file):
FILENAME was read\n
Your program should catch the exceptions if there are.
CSE 205: Object-Oriented Program & Data
