this question is about Java Generics:

when do we write and when we write Node in the linkedList? what do they mean. Go one by one and explain and Node on every question (like why they are positioned this way, what are their physical meaning )

1. public static  Node listPosition(Node head, int position)

2. public static  Node listCopy(Node source) 

3. public E find(Node obCurrent, E obSearch)

4. public void add(E obVal) { this.obHead = add(obHead, obVal); }

5. private Node add(Node obCurrent, E obRef) { if(obCurrent==null) { Node obNode= new Node<> (obRef); return obNode; } else { obCurrent.setNext(add(obCurrent.getNext(),obRef)); return obCurrent; } }

6. public boolean delete(E obElem) { this.bDeleted=false; this.obHead=delete(this.obHead,obElem); return this.bDeleted; }
