Assignment #4 will be the construction of 2 new classes and a driver program (the class containing the
main method).
President class
The President class describes information of a president of a club. It has following attributes:
Attribute name Attribute type Description
firstName String The first name of the president
lastName String The last name of the president
academicLevel String
The academic level of the president such
as senior, junior, etc.

The following constructor should be provided to initialize each attribute. This constructor initializes the
value of string attributes to “?”.
public President( )

The following accessor methods should be provided to get the attributes:
public String getFirstName()
public String getLastName()
public String getAcademicLevel()
The following modifier(mutator) methods should be provided to set the attributes:
public void setFirstName(String someFirstName)
public void setLastName(String someLastName)
public void setAcademicLevel(String someLevel)
The following method must be defined:
public String toString()

toString method should return a string of the following format:
Water,Bob(Senior)
where “Water” is the last name of a president, “Bob” is the first name, and “Senior” is the academic level.
So you need to insert “,” or parentheses between these variables.
Note that you can choose a meaningful parameter variable name for each method.
Club class

The Club class describes a club. It has the following attributes:
Attribute name Attribute type Description
clubName String The name of the Club.
numberOfMembers int The number of members of the club
university String The university of the club
currentPresident President The current president of the club
The following constructor should be provided to initialize each attribute. This constructor initializes the
value of string attributes to “?” and the value of integer attribute to 0,

and an object of President using the constructor of the President class.
public Club( )

The following accessor methods should be provided to get the attributes:
public String getClubName()
public int getNumberOfMembers()
public String getUniversity()
public President getCurrentPresident()
The following modifier(mutator) methods should be provided to change the attributes:
public void setClubName(String someName)
public void setNumberOfMembers(int someNumber)
public void setUniversity(String someUniversity)
public void setCurrentPresident(String firstName, String lastName, String someLevel)
The following method must be defined:
public String toString()

The toString() method constructs a string of the following format:
\nClub Name :\t\tSwimming Club\n
Number Of Members:\t87\n
University:\t\tArizona State University\n
President:\t\tWater,Bob(Senior) \n\n
Assignment4
(Note that this part is already done in the Assignment4.java file that is given to you. This explains each
functionality of this class.)
In this assignment, download Assignment4.java file, and use it for your assignment. You do not need to
modify Assignment4.java file. You only need to write Club.java and President.java files.
The following is the description of Assignment4 class.

The driver program will allow the user to interact with your other class modules. The purpose of this
module is to handle all user input and screen output. The main method should start by displaying the
following menu in this exact format:
Choice\t\tAction\n
——\t\t——\n

A\t\tAdd Club\n
D\t\tDisplay Club\n
Q\t\tQuit\n
?\t\tDisplay Help\n\n
Next, the following prompt should be displayed:
What action would you like to perform?\n
Read in the user input and execute the appropriate command. After the execution of each command, redisplay the prompt. Commands should be accepted in both lowercase and uppercase.
Add Club
Your program should display the following prompt:
Please enter the Club information::\n
Enter its name:\n
Read in the user input and set the club name on the club object. Then it will ask a user to enter its
number of members, its university, its president’s first name, last name, and academic level.
Read in the user input and set them on the club object.
Note that there is only one Club object in this assignment. Thus when “Add Club” option is selected more
than once, the new one overwrites the old Club object information.
Display Club
Your program should display the club information in the following format:
\nClub Name :\t\tSwimming Club\n
Number Of Members:\t87\n
University:\t\tArizona State University\n
President:\t\tWater,Bob(Senior) \n\n
Make use of the toString method of the Club class to display this information. The toString method is
used together with System.out.print method.
(System.out should NOT to be used within the toString method.)
Quit
Your program should stop executing and output nothing.
Display Help
Your program should redisplay the “choice action” menu.

Invalid Command
If an invalid command is entered, display the following line:
Unknown action\n
