create
public static <E> HashMultiset<E> create()
Creates a new, emptyHashMultiset
using the default initial capacity.
-
create
public static <E> HashMultiset<E> create(int distinctElements)
Creates a new, emptyHashMultiset
with the specified expected number of distinct elements.- Parameters:
distinctElements
- the expected number of distinct elements- Throws:
java.lang.IllegalArgumentException
- ifdistinctElements
is negative
-
create
public static <E> HashMultiset<E> create(java.lang.Iterable<? extends E> elements)
Creates a newHashMultiset
containing the specified elements.This implementation is highly efficient when
elements
is itself aMultiset
.- Parameters:
elements
- the elements that the multiset should contain
