Write a new method named slice(int beginIndex, int endIndex) that returns a new ArrayList object containing the elements of the calling list between beginIndex (inclusive) and endIndex (exclusive). The calling list should not be modified. This method should throw an IndexOutOfBoundsException if an invalid index is supplied, or if beginIndex is not at least 1 less than endIndex. Example: If list1 is an ArrayList object containing {1, 2, 3, 3, 6, 2, 2, 3, 1, 4}, then calling list1.slice(4,7) should return a new ArrayList object containing the values at indices 4, 5, and 6. The returned list would contain the elements {6, 2, 2}.
