characterAt abstract method
- int position
Returns the single-character sequence of the position
th character.
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
of a Characters
.
An call to chars.characterAt(n)
is equivalent to chars.elementAt(n).characters
,
or to chars.getRange(n, n + 1)
(except that getRange allows n
to be larger than length).
Implementation
Characters characterAt(int position);
