Question 55
Correct Answer: A
The forEach method accepts a Consumer as its argument. A proper implementation of a Consumer that prints each element of the list is: Consumer<String> function = (String f) -> System.out.println(f); The other options involve different functional interfaces such as Supplier, Predicate, and Function, which are not appropriate for use with forEach.
Discussion
Galen86Option: A
In fact, the above answers are all wrong A seems correct, but the writing in lambda is wrong If rewritten as # Consumer function = s -> System.out.println(s); to compile normally
d7bb0b2Option: A
A is correct cause foreach accept consumer interface
d7bb0b2
NOTICE: A is the correct but consumer is bad implement in the option because explicit paramater for lambda is (String f)->... and the compiler expect Object, the correct is : 1- Consumer x = x -> System.out.print(x) or: 2- Consumer<String> x = (String f) -> ..... o 3- Consumer<String> x= f -> sout...
[Removed]Option: B
Actually answer A is also incorrect. As Consumer is actually Consumer<Object> so it expects an Object rather than a String. It would've worked if it were: f -> System.out.println(f);

forEach() accepts a Consumer, correct answer is A.
Mukes877Option: A
forEach() accepts a Consumer, so correct answer is A.
Ankit1010Option: A
