Creating a String[] from Guava's Splitter

Question

Is there a more efficient way to create a string array from Guava's Splitter than the following?

Lists.newArrayList(splitter.split()).toArray(new String[0]); 

Answer 1

Probably not so much more efficient, but a lot clearer would be Iterables.toArray(Iterable, Class)

This pretty much does what you do already:

public static <T> T[] toArray(Iterable<? extends T> iterable, Class<T> type) {     Collection<? extends T> collection = toCollection(iterable);     T[] array = ObjectArrays.newArray(type, collection.size());     return collection.toArray(array); } 

By using the collection.size() this should even be a tick faster than creating a zero-length array just for the type information and having toArray() create a correctly sized array from that.
