Write a method called deleteAfter to be included in class KWLinkedList that receives two parameters item1 and item2 of type E. The method removes all occurrences of item2 after the first occurrence of item1 and returns the number of items removed from the list. If item1 is not found in the list, the method will not remove any value from the list. Use ListIterator of class KWLinkedList and its methods. Example: item1: 10 item2 : 20 Iist (before method call): 7 20 9 10 20 14 15 20 Iist (after method call) : 7 20 9 10 14 15 It returns 2 Method heading: public int deletetAfter(E item1,E item2) {
