And use charAt . Since the String is implemented with an array the charAt method.. charAt . Since the String is implemented with an array the charAt method is a constant time operation. String s ...stuff... for.. String s ...stuff... for int i 0 i s.length i char c s.charAt i Process char That's what I would do. It seems the easiest..

Fastest way to iterate over all the chars in a String http://stackoverflow.com/questions/8894258/fastest-way-to-iterate-over-all-the-chars-in-a-string long string for int i 0 n str.length i n i char c str.charAt i Or this char chars str.toCharArray for int i 0 n chars.length.. I'd like to know is if the cost of repeatedly calling the charAt method during a long iteration ends up being either less than.. 9 different techniques see below shows that using String.charAt n is the fastest for small strings and that using reflection..
