Hi Guys! I'm having trouble on briefcases having the same value. for ex:
i choose briefcase 1 = 5000, briefcase 2 = 5000

how do i make the briefcases have a unique value?
Note: the value of briefcases are randomized

you can't ... either they are random, or the possible values are limited by already existing values (in which case, they're no longer random).

what you can do is add the already chosen values to a list. When generating a new value:

List<Integer> already; // ..

Integer newValue = getNewValue();
while(already.contains(newValue()){
  newValue = getNewValue();
}
attachToBriefcase(newValue);

Hi,
Can you please share some more details about what you are trying to achieve here.
Thanks

stultuske: Sorry but I did not understand. I tried to run, the code. I could see buttons with numbers from 1 to 10 and a reset button. If you click on a button, it generates a random number. I figured out that its a game of some sort but need a little more to understand what he was trying to do.
