How to get submap of LinkedHashMap by element index?

Question

I am trying to get a submap of LinkedHashMap based on element index. Am I reinventing the wheel here? Sounds like this should be somewhere in API already:

public <K,V> LinkedHashMap<K,V> subMap(LinkedHashMap<K,V> map, int fromIndex, int toIndex) {
    LinkedHashMap<K,V> result = new LinkedHashMap<K,V>();

    int i=0;
    for(Map.Entry<K,V> entry : map.entrySet()) {
        if(i >= fromIndex && i < toIndex) {
            result.put(entry.getKey(), entry.getValue());
        }
        i++;
    }

    return result;
}

Is this the way to go or there are some other better/existing solutions (within Java 6 API).

Answer 1

NavigableMap allows you to get a sub-map back, but it requires that you specify a 'from key' and a 'to key', so you can't do it purely on index.

I'm not aware of any other way of doing this via the standard API.
