specification
-------------

when the program starts the user should have a choice of placing bets or drawing the lottery numbers.

Placing Bets
-------------

The user is allowed to place any number of bets. Each bet is a 6 different numbers between 1 and 49(inclisive) and costs one pound. Each bet must be accompanied by the user name:there are no tickets in this lottery.The user should also be able to place a 'Lucky Dip' bet in which the program chooses 6 random nmbers for them.

Note:The maximum of 20 bets can be placed before the lottery is drawn.


Drawing lottery numbers
------------------------


The winning numbers will be different numbers between 1 and 49,which are randomly choosen. After the wining numbers are drawn your progream should print the list of people who have won.


The different ways of winning are as follows:


1 correct number 3$
2 correct numbers 6$
3 correct numbers 25$
4 correct numbers 750$
5 correct numbers 50000$
6 correct numbers 5000000$


After the winners names and amounts have been printed the program should print the amoubt of loss/profit the lottery has made.The loss/profit is the difference between the amount of money taken in bets and the amount of money paid out in winnings


Tips:
-----

The numbers for the bets should be stored in 2 dimensional array.

We don't do homework here.

Just two hints:

If "any number of bets" should be possible, arrays make your life harder. In that case it would be better to use an ArrayList<int[]> object (if you use JDK1.5 or higher).

Make sure that when getting random numbers, no number is generated twice in one round.
