hi all!!
i want to pass to the Long constructor a value. Accordingto the Certification book u have to pass the value as a string. When i do the following, both work.
Long l = new Long("456");
Long l = new Long(456);
The second version u are not passing within qoutes "". But it still works. Can any1 give explanation!!!

From API:
The class Long has two constructors:
Long(long value)
Long(String s)
I think this itself answers your question.

Maala,
If you remember which one, go ahead and post it in the Errata so that others don't get misled.
Thanks!
