public class DesertEvent {

private static int eventCount = 0;

private String barCode;

private String location;

private String eventType;

private int quantity;

private int capacity;

private int seatsTaken;

public DesertEvent(String eventName, String eventType) {

this(eventName, eventType, 0);

generateBarCode();

}

public DesertEvent(String eventName, String eventType, int capacity) {

}

private void calcMaximumSeats(String eventType) {

switch (eventType) {

case "Workshop":

location = "Library Meeting Room 28";

capacity = 30;

break;

case "Seminar":

location = "High Rise 151";

capacity = 100;

break;

case "Career fair":

location = "Fitch Hall 28";

capacity = 100000000;

break;

default:

break;

}

private void generateBarCode() {

Random rand = new Random();

int randNum = rand.nextInt(90000) + 10000;

barCode = eventType.substring(0, 3) + "-" + randNum + "-" + eventCount;

}

public boolean bookSeats(int numOfSeats) {

if (numOfSeats <= getAvailableSeats()) {

seatsTaken += numOfSeats;

return true;

} else {

return false;

}

public String toString() {

return "Event Name: " + eventName + "\nEvent Type: " + eventType +

"\nLocation: " + location + "\nQuantity: " + quantity +

"\nCapacity: " + capacity + "\nSeats Taken: " + seatsTaken +

"\nBar Code: " + barCode;

}

How would I implement the Driver class that lists the 4 events with format of: generated bar code, followed by event name, event location, and number of seats that are remaining for the event?

The Driver class (TestDesertEvent)

four event objects, each an object of the class type

DesertEvents, in the main method:

DesertEvent event1 = new DesertEvent (“Success in Life ”,

“Workshop”);

DesertEvent event2 = new DesertEvent (“Seminar Prep”,

“Seminar”, 50);

DesertEvent event2 = new DesertEvent (“Working with others”,

“Workshop”, 10);

DesertEvent event3 = new DesertEvent (“career fair”, “Career

fair”)

Then, the program should display a welcome message and the following menu to

choose from:

Please choose one of the following:

L – list all available events

IR – individual registration

GR – group registration

Q – quit

The menu should be displayed by calling a static method inside DesertEvent class

called displayMenu(). The menu should keep repeating until the user chooses to quit. See

sample outputs below:
