Yield Return In Java

Question

I've created a linked list in java using generics, and now I want to be able to iterate over all the elements in the list. In C# I would use yield return inside the linked list while going over the list of elements contained in the list.

How would I go about creating a java version of the above where I can iterate over all the items contained in the linked list?

I'm looking to be able to write code ala

LinkedList<something> authors = new LinkedList<something>();
for (Iterator<something> i = authors.Values ; i.HasNext())
      doSomethingWith(i.Value);

And was thinking that the Value 'property'/method would consist of code resembling

LinkedListObject<something> current = first;
While (current != null){
 yield return current.getValue();
 current = current.getNext()
}

Edit: Notice that I'm not interested in using any 3rd party APIs. Built-in java functionality only.

You can return an anonymous implementation of Iterable. The effects are pretty pretty similar, just that this is a lot more verbose.

public Iterable<String> getStuff() {
    return new Iterable<String>() {

        @Override
        public Iterator<String> iterator() {
            return new Iterator<String>() {

                @Override
                public boolean hasNext() {
                    // TODO code to check next
                }

                @Override
                public String next() {
                    // TODO code to go to next
                }

                @Override
                public void remove() {
                    // TODO code to remove item or throw exception
                }

            };
        }
    };
}
