As per the java documentation says :
The Iterable<T> allows an object to be used as the target of a for-each statement.
In java we can do the following :
for (final <? super T> : T[]) {...}
In this case, why java cannot consider an object of type T[] as being an Iterable, Because the following crashes with an incomptaible types compilation error :
final Iterable<T> anIterable = T[];
An Iterable is an object all unto itself. An array is an object all unto itself. These two things are not the same object or the same type or the same anything. They have literally no relationship - hierarchial or otherwise - between themselves.
Fortunately, the enhanced-for statement is overloaded to accept both arrays and Iterable<T>, so you don't need to fuss with this.
