Which of the following is a valid declaration of a generic method ?A public static<X,Y extends X> boolean isPresent(X x,Y[] y){}
B public static<X,Y extends X>static boolean isPresent(X x,Y[] y){}
C public static boolean<X,Y extends X>isPresent(X x,Y[] Y){}
D None of these
Choice A is the correct answer
generic methods are methods that are parameterized by one or more type parameters.Generic methods allow type parameters to be used to express dependecies among the types of one or
more arguments to a method and/or its return type.The type parameters must be declared before th return type of the method,but after the modifiers.This condition is satisfied by choice A, But not by choices B and C.So choices B C and D are incorrect.
