Sum of the digits

Question

I am trying to write a method which returns the sum of the digits of any integer number.
public class sumofdigits {
    public static int sumofdigits (int number){
         String numberString = Integer.toString(number); // i have changed integer to string.
         int length = numberString.length();
         for(int i = 0; i<length; i++ ){
              String str = String.valueOf(numberString.charAt(i)); // i have changed the char to string
              int n = Integer.parseInt(str);  // then i have changed the string to integer
              int sum = 0;
              sum = sum + n;
              return sum;     
    public static void main(String[] args) {
         System.out.print(sumofdigits(309283));     
}I don't know how to change char to integer so i changed char to string then i move from string to integer...
but it gives missing return statement error... Where am i doing wrong?

Answer 1

Yea i got it ! :)
public class sumofdigits {
    public static int sumofdigits (int number){
         int sum = 0;
         String numberString = Integer.toString(number);
             int length = numberString.length();
         for(int i = 0; i<length; i++ ){
              String str = String.valueOf(numberString.charAt(i));
              int n = Integer.parseInt(str);
              sum = sum + n;
              return sum;
    public static void main(String[] args) {
    System.out.print(sumofdigits(309283));     
}Can you tell me how do i change char to integer and integer back to char?
