Change value via Iterator

Question

Hi,
i have a code:
Iterator<? extends LatLon> foobar = subsetBuffer.getLocations().iterator();
                while(foobar.hasNext())
                    LatLon coo = foobar.next();
                    LatLon popcoo = XProj.GKSlo2WGS84(coo.getLatitude().getDegrees(), coo.getLongitude().getDegrees());
                    coo = popcoo;
                    System.out.println(popcoo);
                }Where i get iterator and do something with its value (popcoo) and then i want to save that popcoo back to iterator. You know what i mean? I want to change value via iterator.
Line coo = popcoo, doesn't work. How should i do that?

What if i have a iterator like this:
Iterator<double[]> foo2 = subsetBuffer.getCoords().iterator();
if i say here foo2.next()[0] = 2, the value doesn't write back into that variable.Yes, that change will be reflected in your original collection.
What you seem to be confusing is that in one case you would like to change the collection to contain a different object, while in the other case you want to modify an object that is contained in the collection:
Can i somehow transform double[] data type to Double[]? You can't, except by creating a new Double-array, so you couldn't influence the original object in any way.
Then i could change a value, right?No, there's no difference between double and Double in this respect.
