Nthis problem you’ll add a countnegative method to an existing linked list implementation. you should create a public non-final class named yoursimplelinkedlist that extends simplelinkedlist. your class should override protected int countnegative() and return the count of the number of items in the list with values less than zero. note that this list only stores ints, not objects, so you do not need to cast item values to work with them as ints. while there are both recursive and iterative solutions to this problem, we expect you to solve it iteratively by following references from the start to the end of the list. public class simplelinkedlist
