Java Programming: Ch 8 Case Problem 1

In previous chapters, you developed classes that work with catering event

information for Carly’s Catering. Now modify the Event and EventDemo classes

as follows:

Modify the Event class to include an integer field that holds an event type. Add a

final String array that holds names of the types of events that Carly’s caters—

wedding, baptism, birthday, corporate, and other. Include get and set methods

for the integer event type field. If the argument passed to the method that sets

the event type is larger than the size of the array of String event types, then

set the integer to the element number occupied by “other”. Include a getmethod

that returns an event’s String event type based on the numeric event type.

To keep the EventDemo class simple, remove all the statements that compare

event sizes and that display the invitation Strings.

Modify the EventDemo class so that instead of creating three single Event

objects, it uses an array of three Event objects. Get data for each of the objects,

and then display all the details for each object.

Save the files as Event.java and EventDemo.java.
