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

You can use functional operation for a more neat code

Set set = new HashSet();

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