Dear friends,
This code gives a compiler error: Can only iterate over an array or an instance of java.lang.Iterable

Kindly provide me the explanation of this compiler error

Regards,
Vijay

The enhanced for loop in Java 5 works with the new Iterable interface which encapsulates an Iterator.

In your example, you are returning an Iterator instead of an Iterable.
