    Post Checking Code: Getting the Unicode value of each character from a string.

    /* Something is wrong here not exactly sure i am a beginner. I cannot use ANY classes.
    EXAMPLE: if argument value is "ABC" then the return value should be "198".
    Help! Thanks in advance*/

    public class Test {

    public static void main(String[] args) {
    addChars("ABC");
    }
    public static int addChars ( String s ) {
    int sum = 0;
    for (int i=0; i<s.length();i++) {
    if(s.charAt(i) <= s.length()) {
    sum += (int)s.charAt(i); // adds Unicode value to sum

    }
    else {
    return 0;
    }
    }
    return sum;
    }
    }

    I'm not entirely sure what you mean, but have a look at what this line is doing, is it ever true?

    if(s.charAt(i) <= s.length())

    Well every character has value i have to produce that value. I would believe that it is true. My string is "ABC" so as i access the string with s.charAt(i) grabbing that first character 'A' it is less than or equal too the length of the String.
