How to Iterate over a Set/HashSet without an Iterator?

Question

How can I iterate over a Set/HashSet without the following?

Iterator iter = set.iterator();
while (iter.hasNext()) {
    System.out

You can use an enhanced for loop:

Set set = new HashSet();

//populate set

for (String s : set) {
    System.out.println(s);
}

Or with Java 8:

set.forEach(System.out::println);
