Basic Java Loops Help

PROBLEM: Ask the user for an integer, add up all of the individual digits the integer, and add up all the individual digits in the result etc. Stop when you have a digit less than 10.

ex. 12345 = 1+2+3+4+5 = 15 = 1+5 = 6.

You can use for loop or do while loop

// for loop
for(int i = 0; i < 10; i++) {
    // code here
}

// do while loop
int i = 0;
do {
    i++;
    // code here
}
while(i < 10);
