Hi Sam,
I am wondering if they are going to ask about some API like collection API (like what's difference between ArrayList and vector or HashMap and WeakHashMap)...
Nope.
... or something special about RMI or Serialization, are they? I don't how can I spend two hours for this exam?!!
They might ask you why you chose one over the other.
Don't spend two hours if you finish in an hour. Just make sure your answers reflect what you did.
Hope this helps,
