use charAt() to access each char, which is an integral value.

Java doesn't use ASCII, it uses Unicode; but for your purposes, Unicode is a superset of ASCII.

In Java, as in C and many other similar language, a character is an integral type; it is it's own "ASCII code". You can just cast a char to an int, although even that isn't needed most of the time:

int asciiCode = (int) myChar;
