Java ArrayList swap

Hi All,

Is there any way of swapping 2 entries in an ArrayList without taking one out into a holder, moving the second and then putting the holder item back in?

i.e. I want to do ArrayList.swap(i,j).

At the end the objects in slot i and j would be in slot j and i resectively.

Re: Java ArrayList swap

Even if there was the overall process would remain the same meaning that performance wouldn't benefit.

Having a look I can't see anything in ArrayList or Vector...
