can we remove floating zero before decimal point in BigDecimal

Question

BigDecimal bd1= new BigDecimal(0.000);
bd1 = bd1.setScale(2, RoundingMode.HALF_UP).stripTrailingZeros();
System.out.println("bd1 value::"+ bd1);

I get the following 0.00 for bd1, but I want bd1 as .00 not as 0.00. Am I applying the methods correctly?

You can do this with `java.text.DecimalFormat`. – user207421 Jul 13 '15 at 05:24 — user207421, Jul 13 '15 at 05:24

You can convert the BigDecimal to a String, and then use a regex to conditionally remove the leading zero, if it exists:

BigDecimal bd1 = new BigDecimal(0.000);
bd1 = bd1.setScale(2, RoundingMode.HALF_UP).stripTrailingZeros();
String bdString = bd1.toString().replaceFirst("^0+(?!$)", "")
System.out.println("bd1 value::"+ bdString);
