Generating a random number based on the values I want (Sorry if vague)

[chanshaw]

Alright I'm not sure if I worded the title correctly but I'm looking to generate a random number based on the numbers in an arraylist.

So if I have the values 1,2,12,6 I would like to generate a random number based on those numbers, so the return number from the random number generated would be either 1, 2, 12, or 6 and nothing else. Hope I explained that well enough, I apologise if not. Thanks guys.

Ok after walking down to dinner it sort of blinged in my head that i could just count the arraylist then generate a random number and based on that value and i could reference the index and the value, thanks anyways!

As the OP wrote: s/he found the answer: build an array { 1, 2, 12, 6 } and generate a random number in the range [0, array.length)

kind regards,
