How to use zero as prefix if value less than equals to 9

Question

How to add zero as prefix if value less than equals to 9, i am using below way of achieving this:

            int countZero = 0;

            if(countVat <= 9)
            {
                countVat = countZero + countVat;
                Log.d("countVat:", String.valueOf(countVat));
            }

but this not works for me, still getting single digit if countVat value less than equals to 9.

You are summing two int's. Convert them to String before summing. — Leonardo Cardoso, Jul 07 '14 at 08:13
int countZero = 0; if(countVat <= 9) { String str = "0" + countVat; Log.d("countVat :", str); } — Aniruddha, Jul 07 '14 at 08:47
