Sum of Digits
Logic: 513 -> 5+1+3=9
| n | res | n | sum |
| 513 | | | 0 |
| 513%10 | 3 | | 3 |
| 513/10 | | 51 | 3 |
| | | |
| 51%10 | 1 | | 4 |
| 51/10 | | 5 | 4 |
| | | |
| 5%10 | 5 | | 9 |
| 5/10 | | 0 | 9 |
| Program | Output |
//Note: Scanner class work with JDK1.5 or above
import java.util.*;
class SumDigits
{
public static void main(String args[])
{
int n, res;
Scanner scan= new Scanner(System.in);
System.out.println("Please Enter No.: ");
n1=scan.nextInt();
while(n>0)
{
res=n%10;
n=n/10;
sum+=res; //sum=sum+res;
}
System.out.println("Second No: " + n2);
}
}
