which collection class offers constant time performance for the basic operations- add(), remove(), contains() and size() ?
Options:
1. TreeSet
2. HashSet
3. BitSet
4. None
Above is a question from Whizlab.
Is BitSet included in syllabus of scjp 1.5?

It doesn't matter. They all inherit from the Set interface, so if you are familiar with the basic functionality of the Set interface, you will know the basic functionality of any class or interface that extends from the Set interface.
To answer your question: I am not aware that BitSet is 'officially' part of the objectives.
