3. public static void main(String[] args) {

4. int num = 989989,rem,sum=0, count =0,temp;

5. temp=num; // store it in temp

6. do

7. {rem=num%10; // finds remainder

8. num=num/10;

9. count++;//increments counter

10. sum+=rem; //adds remainder to sum

11. }while( num>0);

12. System.out.println(“Given Number” + temp);

13. System.out.println(“No of digits=” + count);

14. System.out.println(“Sum of digits=” +sum);

15. }

16. }//end of class

Output: Given Number989989 No of digits=6 Sum of digits=52
