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.println(iter.next());

}

Answer 1

You can use an enhanced for loop:

Set<String> set = new HashSet<String>();

//populate set

for (String s : set) {

    System.out.println(s);

}

Or with Java8

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