The iterator()
appears in Iterator and Collection as the Javadoc is different. In AbstractCollection it is different again, but doesn't appear to add much value.
Why Iterator<E> iterator() is put in Collection, AbstractCollection when already in Iterable [duplicate]

When Iterator iterator()
is put in Iterable
interface and this is extended by Collection
interface and AbstractCollection
interface, why this is again mentioned in Collection
/AbstractCollection
as no definition is given for this in abstract class.
Please help me to understand what I am missing in this from design perspective

Well Iterable is since 1.5 whereas Iterator and Collection are since 1.2. Not sure why AbstractCollection defines it again though, it's javadoc is slightly different though.
