Iterate to find a Map entry at an index?

Question

I have a LinkedHashMap. I want to get the Foo at index N. Is there a better way of doing this besides iterating until I find it?:

int target = N;
int index =

Guava library can help in this case:

public static  T com.google.common.collect.Iterables.get(Iterable iterable, int position)

see javadoc: Iterables.get

For your case the code can be like this:

Iterables.get(foos.values(), N);
