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 insid

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

public Iterable getStuff() {
    return new Iterable() {

        @Override
        public Iterator iterator() {
            return new Iterator() {

                @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
                }

            };
        }
    };
}
