I've found that I often need to iterator over a Map and do something
to each element of the Map. The only way I've found to do this is to
get a get a KeySet from the map, get an Iterator from the KeySet and
use that Iterator to move over the elements of the Map.  Is their a
simpler (less verbose) way of accomplishing this:

Set<String>  keys=myMap.keySet();
Iterator<String>it=keys.iterator();
while (it.hasNext())
{
String key=it.next();
String value=myMap.get(key);
/*
Do something to the value...
*/
}

This just seems like a lot of work when you compare it to what you can
do with a ArrayList (assume this is a list of Strings for example
purposes)
for (String s: myList)
{
//Do something with s
}

Any advice appreciated.
