Specify custom format for DecimalFormat Class

I am trying to represent an integer in 12 digit format, 10 digit format etc with leading zereos. I have used this:-

DecimalFormat decimalFormat = new DecimalFormat("000000000000");
String invoiceAmountString = decimalFormat.format(IntegerValue);

I want a generic function such that when i pass 10 or any other value it should use that number of zereos in DecimalFormat. I have an idea like this;-

case 10:
DecimalFormat decimalFormat = new DecimalFormat("0000000000"); // 10 digit
case 12:
DecimalFormat decimalFormat = new DecimalFormat("000000000000"); // 12 digit

but decimal format can go from 5-25 digit. I need a function like:-

convertToFormat(Integer amount, Integer noOfDigits)

such that if i pass 5,10,15 or whatever value in noOfDigits it should use that number of zereos in DecimalFormat.

try this

String s = String.format("%0" + numberOfDigits + "d", amount);
