What is the right way to change an Integer in a Vector in Java (j2me)
As a follow up to my question about j2me dynamic arrays, I'm now trying to figure out a way to change the values of the Integers in my Vector. Say I have a Vector v, and Array arr, and ints x, y and i; In c++ I could do: v[arr[x][y]] += i; In j2me the best way I found so far to do the same is: v.setElementAt(new Integer(((Integer)...
