I was just doing some of the practice exam for SCJP 1.4
i came across a string related question

and it asks you what the result is..

I think the compilation would fail, wouldnt it. Since d is a String object, and i don't think you can call append() on String..you could do that with a StringBuffer....

please let me know.

Many thanks..

Sounds like a compilation error

If you're preparing for the exam, my advice is to write lots of code to test and verify your understanding. That way, you get the practice, immediate feedback, and reinforcement.

(Besides, you could probably test this in less time than it took to post. )

A 30 second check of the String API would hurt you.

Getting someone to think and try something out is much more useful than just telling them the answer.
