Question

I want to implement a method like this:

public Iterator<File> getFiles(String root) {   // return an Iterator looping through all files in root and all files in sub-directories of roots (recursively) } 

In C#, this can easily be implemented with the yield return keyword. In Java, I suspect I have to end up writing a lot of complicated code to get it done. Is there any good solution to this problem?

Edit: I want the returned Iterator to be ‘lazy’, i.e. only return a new File when next() is invoked. (That is the behavior C#’s yield return offers.)
