Question

The functions are with printAll I think is right and the other function is definite

Answer 1

If DictionaryADT is a class with all the actual implementation, then you need to call

I believe you have Map inside DictionaryADT then, something like

public Collection values() {
    return dictionary.values(); 
}

to get the keys, Iterator is changed to Set

public Set keys() {
    return dictionary.keySet(); // return Set, Please perform all the set opetations.
}

I believe this what you are looking for.

Thanks, Bennet.
