Question

I'm looking for a class from the Java Collection Framework that would not allow null elements.

Do you know one?

Answer 1

Most Queue implementations (with the notable exception of LinkedList) don't accept null.

EnumSet is a special-purpose Set implementation that doesn't allow null values.
