Java Programming: Ch 6 Case Problem 1
Carly’s Catering provides meals for parties and special events. In previous chapters, you developed a class that holds catering event information and an application that tests the methods using four objects of the class. Now modify the EventDemo class to do the following:
Continuously prompt for the number of guests for each Event until the value falls between 5 and 100 inclusive.
For one of the Event objects, create a loop that displays “Please come to my event!” as many times as there are guests for the Event.
Save the modified file as EventDemo.java.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Please use code to answer question:
import java.util.Scanner;
public class Event {
public final static double LOWER_PRICE_PER_GUEST = 32.00;
public final static double HIGHER_PRICE_PER_GUEST = 35.00;
public final static int CUTOFF_VALUE = 50;
public boolean largeEvent;
private String eventNum;
private int numOfGuests;
private double price;
private double pricePerGuest;
public Event(String event, int guests) {
eventNum = event;
numOfGuests = guests;
}
public Event() {
this(\"A000\", 0);
}
private Scanner input = new Scanner(System.in);
public void setEventNumber() {
System.out.print(\"What is the event number? \");
eventNum = input.nextLine();
}
public void setNumOfGuests() {
System.out.print(\"How many guests are attending the event? \");
numOfGuests = input.nextInt();
if (isLargeEvent())
pricePerGuest = LOWER_PRICE_PER_GUEST;
else
pricePerGuest = HIGHER_PRICE_PER_GUEST;
largeEvent = (numOfGuests >= CUTOFF_VALUE);
price = numOfGuests * pricePerGuest;
System.out.println(\"\");
}
public boolean isLargeEvent(){

return true;
