Use only a certain digit in a number

-----------------------------------

hey there quick question. This say i am given a number "12345", how would i go about just getting one digit out of that? so that i could pull all the numbers out and go 1+2+3+4+5+6 and stuff like that

if its a string, then its fairly easy
for (int i = 0 ; i < number.length(); i++)
  sum += Character.getNumericValue(number.charAt(i));
if its not a string, then you can just go
while (temp>0){
 digit = temp%10;
 temp /= 10;
}

Remember that 12345 = 1 * 10000 + 2 * 1000 + 3 * 100 + 4 * 10 + 5 * 1.
