I would have thought this question would have been answered before, but can't seem to find anything about it.

My question is as the title says, why does creating a sublist from index to index, not return the total number of indexes I'd expect? 

A more detailed example:

```
List slice = points.sublist(20, 48);
Log.i(TAG, slice.size());

```

I would expect the log to return 29 in the example above, but in actual fact it returns 28.

Why does this happen and what is the correct solution to this? To add +1 to the second index, or -1 to the first index?
