Question

Personally, I find the range of functionality provided by java.util.Iterator to be fairly pathetic. At a minimum, I’d like to have methods such as:

• peek() returns next element without moving the iterator forward
• previous() returns the previous element

Though there are lots of other possibilities such as first() and last().

Does anyone know if such a 3rd party iterator exists? It would probably need to be implemented as a decorator of java.util.Iterator so that it can work with the existing java collections. Ideally, it should be ‘generics aware’.

Thanks in advance, Don
