A synchronized Set is not concurrent. A synchronized Set will only accept one thread at a time whereas a concurrent Set can accept a plurality of concurrent threads. Hence its name.

What about using Collections.synchronizedSet(new HashSet(…)); ?

You are absolutely right Louis. Thanks for pointing out that. I have updated the post accordingly.

Your addIfAbsent method seems exactly equivalent to the perfectly normal Set.add method, which already returns true if and only if the element was previously absent and has since been added.
