Java Programming: Please complete all the questions. Thank you in advance.

1. What is the output from the following code? Node pnew Node "PACK"); Node qnew Node ("RAT", p); Node pointer q; while (pointer null) ListIterator iterlist.listIterator iter.next( iter.add (21); Indicate the value returned by the method call value = list.get(2); Ans: System.out.println (pointer.data); 5. Given the statements below: LinkedList list new LinkedList ); list.add (10); list.add (12); list.add (25) 13tIterator ter = 113t . 113tIterator (1); iter.previous ( iter.remove) Indicate the value returned by the method call value = list.get(0); Ans: pointer pointer.next; Output 2. Given the statements below, indicate the value displayed. LinkedList list new LinkedList); list.add (5) list.add (12); list.add (21) L1 st Iterator iter = list. listterat r( ); iter.next() if (iter.hasPrevious()) System.out.print (iter.previous ()) 6. Given the statements below Linkedlist list = new Linkedist( ); list.add (6) list.add (17) 13tIterator ter 11st. listterator ( ); iter.next) iter.set (25); Indicate the value returned by the method call value iter.previous Ans: else System.out.print (iter.next()) Ans: 3. Given the statements below LinkedList list new LinkedList(); list.add (10); list.add (12); list.add (25); ListIterator iter list.listIterator (1ist.size() if (iter.hasPrevious )) 7. Given the statements below LinkedList listnew LinkedList() list.add (6); list.add (18); list.add (26) ListIterator iter list.listIterator (1); Indicate the value returned by the method call value iter.next ( ); Ans: System.out.println (iter.previous ) else system.out.println (-1); Indicate the value displayed on standard output. Ans: 4. Given the statements below Linkedilst list new Linkedist( ); list.add (7) list.add (14)
