Hi Folks,
I would like to draw your attention to Chapter 1 SelfTest question 6 in the Kathy Sierra and Bert Bates book for OCPJP6. The correct answer is
A: Compilation succeeds
Shouldn't the answer be
E: Compilation fails with an error on line 7
? My rationale is that since Phone3 class is implementing Device interface, it should implement it's doIt() method.
Hope somebody can explain. Thank you.
