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         


        

Answer 1

Enumeration(?):

Enumeration e = new Vector(set).elements();
while (e.hasMoreElements())
    {
        System.out.println(e.nextElement());
    }

Another way (java.util.Collections.enumeration()):

for (Enumeration e1 = Collections.enumeration(set); e1.hasMoreElements();)
    {
        System.out.println(e1.nextElement());
    }

Java 8:

set.forEach(element -> System.out.println(element));

or

set.stream().forEach((elem) -> {
    System.out.println(elem);
});
