HashMap<String, ArrayList>

[Eugene Wright]

I've created a Hashmap like the following HashMap<String, ArrayList> myMap = new HashMap<String, ArrayList>();

I've added my keys and values, and I understand how to do a straight iteration through my HashMap, but how do I access only the "5th" item in the ArrayList (just as an example).

So I know the 5th item in the ArrayList for each of the hashmap values will be a phone number, I want to iterate through the HashMap and only grab that 5th value.

Thanks

Eugene: As you described, you first get the keySet() of your Map and then
using for(each), iterate through this Set, get() each List and pick up its 5th element.

myMap.get("Eugene").get(4);

. . . which will of course throw a NullPointerException if the name "Eugene" doesn't appear as a "key".

But you have a serious design problem. Why on earth is the phone number the 5th item in the List? Why haven't you created a class to encapsulate all those values?
