Is there any equivalent to Collections.getOnlyElement() that works with arrays?
I’m aware it’s a trivial function to implement, but Collections.getOnlyElement() is as well, and it’s in guava.
Iterators.getOnlyElement(Iterators.forArray(array))By using
Iterators.forArray, you can bypass the need to create a copy of this array as a list, and instead iterate over the array itself. Then useIterators.getOnlyElementto get the first element from an iterator.
