Practical No. 2: Write a program to design a form using the components List and Choice.

I.        Practical Significance:

The List and Choice components lets the user choose one option from list of available options A Choice is displayed in a compact form that requires  you to pull it down to  see the list of available choices. Only one item may be selected from a Choice. A List may be displayed in such a way that several List items are visible. A List supports the selection of one or more List items.

VI.           Relevant Affective domain related Outcome(s)

                1.     Follow precautionary measures.

                2.     Follow naming conventions.

                3.     Follow ethical practices.

VII.         Minimum Theoretical Background

List: Creates a list from which the user can choose list items.

Constructors:

List () // allows only one item to be selected

List (int numRows) // no of entries will always be visible

List (int numRows, Boolean multiple Select)// if it is true then user select multiple items. If it is false then only one item may be selected

Choice

The Choice class is used to create a pop-up list of items from which the user may choose. When the user clicks on it, the whole list of choices pops up and new selection can be made. Choice defines the default constructor, which creates an empty list. To add a selection to the list, call add ().
