Reading one number from a string (array?)

I would like to have a string variable -- for example: line1 = "0020333334561111111234555500000"; line2 = "A00023454B2345266C23546734D267"; I want to be able to read the 12th character in (in the examples it would be 6 or 3) and do something with that character. A data table of sorts. I know I can do it with commas, but I would like to pack some code together just because. LOL Ideas?

Try something like 
char let = line1.charAt(11)
int num = (int) let.toInt();

Awesome. So if I give a command like: char A01 = row1.charAt(1); How do I use the information? Something like: if (A01 = "1") {addObject(new Object(), X, Y);} I get "incompatible types" with that, but I'm sure it's something I'm setting up incorrectly.

A01 is of char type and "1" is of String type. You cannot compare the two. Also, a single equals sign is used to assign values, not to compare values (like '=='). What you want is 
if (A01 == '1')

So is it possible to do an "if" statement using a char? For example: 
if (A01 == 1) {addObject(new Object(), X, Y);}
Or do I have to convert the char to a string some how?

I read another thread suggesting something like this: 
A00 = row1.charAt(1) - '0';

chars are kinda interchangeable with ints. Each character (google ascii table) has a designated value i.e. '1' != 1 The char '0' has value 48, and the proceeding digits continue from there, so subtracting '0' from a digit char will give the numerical value of the digit
