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

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

Use String.format

String.format("%02d", num);
