I have an array with 280 items in it. I only want 140 of those, so I want to pick them at random. So I need to generate a random number between 0 and the source array's getupperbound property. I think. Is there a more suitable way to pluck an item from an array. I wonder if there's a way to ensure that you don't choose the same item more than once. I suppose I could randomly sort the source array and choose the first 140 items, that would ensure I don't get a repeat item. But could be inefficient if the source array is much larger than the destination array, because I'd be shuffling more values than I need to shuffle. I suppose it's a sampling problem.
