Hi All,

I passed my OCP Programmer II exam today.  When I log into CertView, I see the results of the 1Z0 809 exam, but don't see the link to the OCP certificate.

Will I get an email alerting me that the certificate is available for download?  If not, how long should I wait before I can download the cert?

Thanks.

No! Although it might be for the part on streams, lambdas and predicates. But you have much more interfaces to study: e.g. Runnable, Collection, Set, List, Map, Runnable, Closeable, AutoCloseable, and so on.



Thanks Roel.  In that case, has anyone ever created an comprehensive list of interfaces?  Learning the operations exposed by these goes a long way to understand their concrete implementations.
I was wondering if there's a list of key interfaces that should be learned (or known about) for the Java SE8 OCP exam.  For example, Runnable is one.  The others are the functional interfaces, e.g. BiFunction, Predicate, and so on.  Finally, there are functional interfaces for primitives, such as DoubleToIntFunction, and LongBinaryOperator.

Should I assume that everything in java.util.function is fair game?

@Mikalai Zaikin:  Fantastic!  Thanks very much!
Thanks very much Jeanne!  Loved your book, by the way!

This reminds me to check the Javadoc before I post elementary questions...
Hi, I know that IO classes implement the Closeable interface, and I agree that learning things for an exam isn't the best way to go, but I'm curious: is there a list of classes in Java 8 that implement Closeable?

Am I going to have to go into the exam knowing just those that I've looked at in the OCP book by Oracle?
