asList

[adam Lui]

when we do this...

String[] sa = {"a", "b", "c"};
List sList = Arrays.asList(sa);
 

what implementation of LIst does it actually use?
ArrayList, vector or LinkedList?

[Kelvin Chenhao Lim]

None of the above. It's actually using a private nested class (Arrays.ArrayList) that's not part of the public API. One important property of this class is that it does not support add or remove operations.

Howdy!

For the exam you should also know about the getClass() method from class Object.
