During a bit of careless typing (thinking?) when putting together the ADT for List, the boundary condition for uptoIndex in List.sublist() was given as uptoIndex < size. Below is the specification with the mistake. What are the implications of this? Why is this wrong?
sublist ( int fromIndex, int uptoIndex ) pre-condition: 0 ??fromIndex < size 0 ??uptoIndex < size fromIndex ??uptoIndex responsibilities: provide a sublist (“view”) of this list containing the elements in the positions from fromIndex to uptoIndex – 1 inclusive. The sublist is backed by this list, so changes made to the sublist change this list. Operations on the sublist are undefined if the list is structurally modified in any way except through the sublist post-condition: this list is unchanged throws: index out of bounds exception if pre-conditions are not met returns: a List object containing the elements in the positions fromIndex to uptoIndex – 1, inclusive.
