Quick way to find index of object in arraylist?

818447Nov 24 2010 — edited Nov 24 2010

Hi, I have an arraylist of Doubles, i was wondering if there was any way to get the index of an element inside the list?

indexOf(Object o)

I think this wants me to have a copy of the actual object rather than letting me do this for example:

indexOf(20.5)

Is there any quick way i can do this?
