Which is True?

1) LinkedHashMap extends HashMap and implements Map
2) LinkedHashMap only implements Map (i.e. it's not a subclass of HashMap).

Are you familiar with the javadoc that's shipped with Java? It answers questions like this quite nicely...

It is sorta covered in the JavaRanch Style Guide.
