Generics

Generics, the new feature of Java. Don't really expect to people to be comfortable specially if they have been working in older java versions. But if, candidate is certified SCJP on Java 5, things change. One can expect at least such fellows to be aware of Generics.

Q: So, you are certified SCJP 5 ?
A: Yes.

Q: That means you must be aware of generics ? One of the features introduced in Java 5.
A: Confidently, yes.

Q: Generics. I am sure you know what it is. What benefit does it provide ?
A: Generics !!! (Now started to look puzzled). Generics makes it easy as generic class can be inherited and allows to re-use code in generic class.

Now we are puzzled how does generic class and inheritance come up in Generics. Probably, there was confusion over question. So repeated it and ensured that interviewee understood its GENERICS no GENERIC CLASS.

Still there was no change in answer. Generic class helps in re-use implementation.

With some more such responses we were puzzled whether interviewee actually holds SCJP 5 certificate. So much so we ended up searching for SCJP certificate and to our surprise we found one which looked real.
