6.13 Test and define the following method /** * In a given ArrayList, remove all duplicates. * The worstTime(n) is O(n2 ). * * @param list - the given ArrayList. * * @return - An ArrayList that is identical to list except only the first * occurrence of duplicate elements remains. * * @throws NullPointerException - if list is null. * */ public static For example, suppose myList consists of references to Integer objects with the following values, in sequence 3, 8, 6, 4, 8, 7, 8, 9, 4 Then the ArrayList returned by the call to uniquefy (myList) will consist of references to Integer objects with the following values, in sequence 3, 8, 6, 4, 7, 9 | |
