characterAt abstract method
- int position
Returns the single-character sequence of the
position must be non-negative and less than length.
This operation must iterate characters up to
position to find
the result, just like elementAt.
It is not an efficient way to iterate over the individual characters
An call to
is equivalent to
chars.getRange(n, n + 1)
(except that getRange allows
n to be larger than length).
Characters characterAt(int position);
