Class description

SelectPane

SelectPane class should contain at least the following instance variable:

Attribute name	Attribute type	Description
clubList	ArrayList	a list of club objects.

This class should have a constructor:

public SelectPane(ArrayList clubList)

where the parameter "clubList" is passed from the Assignment6 class. The constructor layouts and organizes nodes/components in this panel. You will be adding more variables (nodes/components) than what is listed here, including check boxes, and labels. An object of some pane (maybe VBox) needs to be created, where check boxes will be added later on, and it needs to be added to this SelectPane.

public void updateClubList(Club newClub)

This method creates an object of CheckBox using the toString method of the parameter object newClub. Then the check box should be added to the pane that was initially added to the SelectPane in the constructor.

This class contains a nested class called SelectionHandler class that implements EventHandler interface. Thus you need to define its handle method that is supposed to check which check boxes are checked, and compute and update the total number of members of selected clubs whenever one check box is checked or unchecked.

CreatePane

CreatePane should contain at least the following instance variable:

Attribute name	Attribute type	Description
clubList	ArrayList	a list of Club objects.
selectPane	SelectPane	an object of SelectPane.

This class should have a constructor:

public CreatePane(ArrayList clubList, SelectPane selectPane)

where the parameter "clubList" is passed from the Assignment6 class and the second parameter is an object of SelectPane. The constructor layouts and organizes components in this panel. You will be adding more variables (nodes/components) than what is listed here, including labels, textfields, a button, and a text area.

This class contains a nested class called ButtonHandler class that implements EventHandler interface. Thus the ButtonHandler needs to have a definition for handle method that adds some information of a club to the list and does error handling. See the UML class diagram for the parameter and return type of this method. In the handle method, you need to extract the information from the textfields. Then you can instantiate an object of the Club class and set its variable values using these values from the textfields. You can use the toString( ) method of the Club object to display the information on the textarea on the right hand side and also add the Club object to the "clubList".

Assignment6 class

Assignment6 extends Application defined in javafx.application package and should initialize itself by setting its size. It contains at least following instance variables:

Attribute name	Attribute type	Description
clubList	ArrayList	a list of club objects. It will be used in both CreatePane and SelectPane.
selectPane	SelectPane	an object of SelectPane.
createPane	CreatePane	an object of CreatePane.
tabPane	TabPane	an object of TabPane. It will contain createPane and selectPane under each tab.

Grading Policy:

• submit assignment on time
• indicate assignment number, name, lecture time, and description of each class clearly in each submitted java file
• 5 pts - Documentation (header with your name, your information, and program description for every class/file and comment/description within your code for every method) 1 pt - Indentation and spacing (easy to read) 6 pts - Required classes/methods and functionalities implemented 8 pts - Your program minimally need to have the following functionalities:

1. 2 points: Appropriate components such as textfields, labels, etc. are shown under the "Club Creation" and "Club Select" tabs.
2. 1 point: When the "Create a Club" button is pushed, the club information is added on the right panel in the correct order and the message of "club added" shows up.
3. 1 point: Error handing in case some field is not filled.
4. 1 point: Error handing in case non integer is entered for the number of members (under Club Creation).
5. 1 point: Whenever a new club is added in the club creation panel, its corresponding CheckBox is added in the club selection pane.
6. 2 points: When a check box in the club selection pane is checked or unchecked, the total number of members for selected clubs needs to be computed and updated in the label to display it.w

You need to add more codes to complete Assignment6, CreatePane, SelectPane.
