Which of the following can fill in the blank to make the code compile?
import java.util.function.*; public class Main { public static void main(String[] s) { Predicate<String> pred = ___ -> true; } }
D.
The type in the lambda must match the generic declared on the Predicate.
In this case, that is String.
Options A and B are incorrect.
While Option C is of the correct type, it uses the variable s, which is already in use from the main() method parameter.
None of these are correct, and Option D is the answer.
