I would like to know how much in depth we are supposed to know of collection topic. I know the different interface in it and the implication of them. But I am confused after solving Dan's test of chapter 11. Do we need to know the different methods for each inteface, iterator methods and all in it.
Hi,
I learned all methods which are talked about in the Kathy/Bert book. There are quite some, but most of the time self explaining.
For example I learned about the
Map method
Set keySet(), but not about the
Map method
Set entrySet(), where Set is the return type.
Offtopic question:
What happens in the
entrySet, if we have duplicate values?
And btw. who is Dan?
cheers
Bob
Edit: changed the post to clarify that
Set is the return type.
