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:

Sorting

Searching

Aggregate Objects Interfaces

Serialization

File read/write

Program Description

Class Diagram:

(https://asu.instructure.com/courses/42647/files/12993483/download? wrap=1)

President

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, presidentl and president2, then, executing the following statement:

presidentl .copy(president2)

should resulting to have the object presidentl to have the same firstName, lastName, and academicLevel value as the ones for president2, but presidentl and president2 should not become aliases.

Club

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

The ClubNameComparator class implements the Comparator interlace (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<Club>.

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

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<Club>.

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

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<Club>.

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

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<Club>)

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

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:

clubList an array of Club objects A list of Club objects in the c

management system

https://asuinstructure.com/courses/42647/pages/assignment8-due-wednesday-march-25th-7-00pm?module_item_id=2689624 7/19

the maximum number of Clu that can be stored in the clul array. It is also the size of thi array.

The following public methods should be provided to interact with the club management system:

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

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:In

https://asuinstructure.com/courses/42647/pages/assignment8-due-wednesday-march-25th-7-00pm?module_item_id=2689624 12/19

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:ln

Read in the string that a user types, say input, then attach
at the end of
the string, and write it to the file. (i.e. input+
string will be written in the file.)

If the operation is successful, display the following:

FILENAME was writtenln

Replace FILENAME with the actual name of the file.

Use try and catch statements to catch I0Exception. 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: In

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):

FILENAME was readln

Then read only the first line in the file, and display:

The first line of the file is:In

CONTENTIn

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 catchstatement to catch, FileNotFoundException, and the rest of I0Exception.)

If the file name cannot be found, display

FILENAME was not foundln

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:In

Read in the filename and write the serialized ClubManagement object (the variable clubManagel) 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 writtenln

Replace FILENAME with the actual name of the file.

Use try and catch statements to catch NotSerializableExeption and I0Exception.

Deserialize ClubManagement from File

Your program should display the following prompt:

Please enter a file name to read:In

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 clubManagel) 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 readln

Your program should catch the exceptions if there are.

(Use try and catch statement to catch ClassNotFoundException, FileNotFoundException, and the rest of I0Exception.)

See the output files for exception handling.
