Java – HashSet is the best way to implement iterators that do not support remove()

I have a class that uses HashSet. I want the class to implement iteratable, but I don't want the class iterator to support the remove () method

The default iterator for HashSet is HashSet Keyiterator, which is a private class in the HashSet class, so I can't simply extend it and override the remove method

Ideally, I want to avoid writing a wrapper class for keyiterator, but I don't know how to easily implement my own iterator in any other way

Any ideas?

Cheers!

Pete

Solution

java.util.Collections.unmodifiableSet(myHashSet).iterator();

java.util.Collections.unmodifiableSet(myHashSet).iterator();
