Is there some trick to convert HashMultiset<String>
to Map<String,Integer>
, except from iterating all the entries in the Set
?
Update: The Integer should represent the count of String in the multiset.
Updated to java 8, here is what I found as the best answer (based on other answers):
public static <E> Map<E, Integer> convert(Multiset<E> multiset) {
return multiset.entrySet().stream().collect(
Collectors.toMap(x->x.getElement(),x->x.getCount()));
}
or:
public static <E> Map<E, Integer> convert(Multiset<E> multiset) {
return multiset.entrySet().stream().collect(
Collectors.toMap(Entry::getElement,Entry::getCount));
}
