java - ArrayLinkedList Insertion Sort -

i have array list insertion sort , teacher sent me , gave me f, says can make before friday. not understand why isn't a.l insertion sort. can me fix hits criteria? thanks.

he said:

after checking first insertion sort did incorrectly. said shift numbers , move number proper place , not swap number place. in assignment in mysa said if 0 assignment.

 import java.util.arraylist;   public class alistinssort {       private static void insertionsort(arraylist<integer> arr) {           insertionsort();      }       private static void insertionsort() {         arraylist<integer> swap = new arraylist<integer>();         swap.add(1);         swap.add(2);         swap.add(3);         swap.add(4);         swap.add(5);          int prior = 0;         int latter = 0;          (int = 2; <= latter; i++)         {             (int k = i; k > prior && (swap.get(k - 1) < swap.get(k - 2)); k--)               {                 integer temp = swap.get(k - 2);                 swap.set(k - 2, swap.get(k - 1));                 swap.set(k - 1, temp);             }         }         system.out.println(swap);     }  } 

first of all, seems teacher asked use linkedlist instead of arraylist. there quite difference between them.

secondly, , maybe more point. in inner loop saving temp variable , swapping elements @ position k - 2 , k - 1 each other. commentary not teacher intended. since wants solve problem element insertion, recommend @ following method definition of linkedlist.add(int i, e e): https://docs.oracle.com/javase/7/docs/api/java/util/linkedlist.html#add(int,%20e).

this should point in right direction.
