Thanks Guys for the hlep, but my real question was why an "enum" type variable refering to a null object is still able to get its constant by using the dot(.) notation, and all the other object type can't do that. Like in the code below:
The output is:
"Monday
Test Class"
NullPointerException for statement "Sys out.prtn(dd.Monday);
The enum type variable is going to print the value "Monday" and then you get the "Test Class", but "dd.Monday" expression gives you NullPointerException, which i understand very well. I just can't understand
why the code is not throwing the NullPointerException. [ September 11, 2008: Message edited by: Shiraz Choudhary ]
