Can you point me in the right direction? I input 564 and 672 and get the right answer, but other digits fail. What am I missing?

Question about the task

Sum of the digits of a three-digit number

Under discussion

package com.codegym.task.task01.task0132; /* Sum of the digits of a three-digit number */ public class Solution { public static void main(String[] args) { System.out.println(sumDigitsInNumber(546)); } public static int sumDigitsInNumber(int number) { //who's idea was this? int n=672; int sum=0; while (n>0) { sum=sum+n%10; n=n/10; sum=sum+n%10; n=n/10; sum=sum+n%10; n=n/10; } return sum; } }

Write the code for sumDigitsInNumber(int number). The method takes a three-digit whole number. You need to calculate the sum of the digits of this number, and then return the result.

Consider this example:
The sumDigitsInNumber method is called with the argument 546.

Example output:
15

Requirements:

The program must not read data from the keyboard.
The sumDigitsInNumber(int) method must be public and static.
The sumDigitsInNumber method must return an int.
The sumDigitsInNumber method should not display anything.
The sumDigitsInNumber method must return the sum of all digits in the parameter number.

while (n != 0)
      {
          sum = sum + n % 10;
          n = n/10;
      }

Here is logic replace line 17 to line 28

Thank you Gellert Varga. I think that I'm forever trying to solve the puzzle mathematically instead of letting the computer think it out. Lol, thanks a million.

Line 10.: This code invokes the line 13 sumDigitsInNumber() method . This code in line 10 sends the "546" int to the method. Line 13.: ...(int number): the method accepts an int, and this int is named here as variable "number". At this moment variable "number" equals to 546. So, in line 15: in this method you need to use this variable "number", and not the "int n = 672;" . I think the logic of the calculating in the method is good!
