Public void duplicateEach( )The duplicateEach method should duplicate each element in the linked list. For instance, if the linked list contains { Apple Banana Melon Orange }, and this method is called, then the linked list will contain { Apple Apple Banana Banana Melon Melon Orange Orange } If the linked list is empty, then it should not change the content of the linked list. I have to write a code for this method, and I did. But when I run the code it didn't work properly. Here's my code:public void duplicateEach( ){Node current = first; while(current != null) { Node temp = current. next; current. next = current; current = temp; }}
