why doesn't this code work? (charAt)

nast777

'l' is a variable being used. I want this code to take the number at location 'l' but I get the message "String Index Out Of Bounds Exception: String index out of range: 4" even though the value of l is less than 4.

if (saved.charAt(l) == 1)

Can you prove that? Add the following debug

println("[" + saved + "]");
println("l:" + l);

1 is and of thing to compare a char to. Do you mean '1'?

@koogs i added what you said to but i still get the same problem. in this case saved = 1001 and 'l' = the length of the string (4).

     println("[" + saved + "]");
            println("l:" + l);
          if (saved.charAt(l) == 1)

@koogs i actually figured it out. I forgot that the first character is 0 not 1. Thanks for your help!
