Answer to Question

Which functional interfaces complete the following code presuming variable r exists? (Choose all that apply.)

6:    ______ x = r.negate();..



Is incomplete.
The Answer states Predicate is correct answer for this line, which definitively is a true statement, but it's not the only possible answer as Bipredicate does also have a .negate() method and is listed to.

Full question and Answer is attached (Screenshot).

I agree with you, it looks like an error in the question.

Also, logged this errata. It is correct in the printed book for what it's worth.

Ok, nice to hear it's only a test-bank problem.

By the way: i found another small issue inside the testbank:

Answer explonation of Question tb584704.JaSE11PrgISG.be2.71 states:

Note that options E and F are always incorrect, as a call to this() or super() cannot come after any other statements in a constructor.



While option E would place a this(3) exacly in the correct place (like described earlyer in the answer), but of course still is the wrong answer due to the compiler error.

Samuel,
Can you supply the chapter/question number. The tb* thing is a key in the exam software, not something I can search by.
