| Post subject: | 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. |

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... |
