Issuing random numbers

Question

Guys please please can somebody help me out, I?m having a problem with my java programme,
My programme issues out seats in a theatre, I have two arrays working in my script, the first is Economy and the Second is Gallery
The first user prompt of the programme is to select where you would like to sit in the theatre. E for Economy, and G for Gallery.
Once this selection is made a random seat number from either the Economy array or Gallery array is printed out depending on where the user chose to sit.
because its a theatre and only one seat can be issued to one person at any one time thus I cant have an array element printed out more than once,
Is there a way of removing deleting or conditioning an array element so that it can not be used again through the duration of the programme?
Or possible is there a simpler method of achieving this.
any advice will be brilliant
this is how my code appears
import java.util.Scanner;
* Write a description of class SquareCube here.
* @author (your name)
* @version (a version number or a date)
import java.util.Scanner;
import java.util.Random;
import java.util.ArrayList;
public class BookingTickets
public static void main (String [] args)
Scanner myScanner = new Scanner(System.in);
double Price = 0.00;
String SeatArea;
int Count;
int[] SeatNumberEconomy1 = {1,2,3,4,5,6,7,8,9,10};
int[] SeatNumberGallery = {11,12,13,14,15};
int NumberSelectorEconomy;
int NumberSelectorGallery;
ArrayList SeatNumberEconomy = new ArrayList(10);
NumberSelectorEconomy = (int)(java.lang.Math.random()*10);
NumberSelectorGallery = (int)(java.lang.Math.random()*10);
for (Count = 0; Count <=14; Count++)
System.out.println ("Please select where you would prefer to sit");
System.out.println ("Input (E) for Economy and (G) for Gallery;- ");
SeatArea = myScanner.next();
if (SeatArea.equalsIgnoreCase("E"))
SeatArea = ("Economy");
Price = 10.00;
System.out.println (" ");
System.out.println ("You have Selected...");
System.out.println (SeatArea + " Priced at ?" + Price + " per ticket");
System.out.println ("Your Seat Number is;- " + SeatNumberEconomy[NumberSelectorEconomy]);
System.out.println (" ");
if (SeatArea.equalsIgnoreCase("G"))
SeatArea = ("Gallery");
Price = 20.00;
System.out.println (" ");
System.out.println ("You have Selected...");
System.out.println (SeatArea + " Priced at ?" + Price + " per ticket");
System.out.println ("Your Seat Number is;- " + SeatNumberGallery[NumberSelectorGallery]);
System.out.println (" ");
System.out.println (" ");
System.out.println("Sorry All Seats have been Booked, Please try again tomorrow");
System.out.println (" ");
}

That sounds great, the numberes i will need to pull out of the bag, as such, will always be 1 to 15.1) Create the Set to hold the seats
2) Iterate from 1 to 15 and add each one to the set.

though i need them to be pulled out in random order it is however imperitive that the same number is not pulled out twice, since im trying to find a method of booking out seats in a theatre it wouldnt make sence.which is why I say use a Set not a Bag.

if you could help with this it would be a great burden lifted off my soulders, Help - yes. Provide code for you to submit as your homework - no!
