Hi All,
For Java cert, do we need to know about Object ordering, Comparable and Comparator interfaces and methods?
also, related to the Collection interfaces, there are Wrapper implementations and Convenience implementations.... Is it ok to skip these topics?
Thanks in advance...

On Marcus Green's tutorial, there is a good explanation of what needs to be known:

Quoted here for convenience:


The exam questions on these new collections are fairly basic, requiring a knowledge of where and how you might use them, rather than a detailed knowledge of the fields and methods.

 
Don't get me started about those stupid light bulbs.
