These questions were asked to me in a Interview for Java Developer by Coforge. Struts 1 flow struts 2 flow functional interfaces Functional Interfaces are interfaces which have only one abstract method. The interface is annotated with the annotation @FunctionalInterface. are functional interfaces method special. No. lambda Expressions max in lambda expressions import java.util.Arrays; import java.util.List; import java.util.Optional; public class Main { public static void main(String[] args) { List nums = Arrays.asList(12, 15, 0, 8, 7, 9, -6); System.out.println("Original values of the said array: " + nums); Optional max = nums.stream().max((x, y) ->x.compareTo(y)); System.out.println("Maximum value: " + max.orElse(null)); } } Annotations assert() assert() is used to verify a statement if it is true the flow is not disturbed if it is false code throws assertionException. testing using junit.
