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

code:

for (int i = 0 ; i < number.length(); i++)   sum += Character.getNumericValue(number.charAt(i));

if its not a string, then you can just go

code:

while (temp>0){  digit = temp%10;  temp /= 10; }

The % operator gives you the remainder after division with /. Remember that 12345 = 1 * 10000 + 2 * 1000 + 3 * 100 + 4 * 10 + 5 * 1.
