About Question enthuware.ocajp.i.v7.2.865 :

[ETS User]

I was thrown by the fact that main() is declared as throwing an Exception, yet the Data class wasn't throwing any. I was expecting a compiler error as a result.

[admin]

A method can be defined to throw any exception even though the code inside it does not throw that exception.

I just had a doubt with the answer.
how the output is 10Y 0Z ?
i got the point of 10Y but why it is 0Z instead of 10Z because the value of x is changed to 10 when the first object is called because objects are passed by reference...

Please advise!

[admin]

There are two Data objects. The first one is created with int 10 and the second one is created with string "Z". Where do you see x being changed to 10 for the second Data object?
