I am dealing with lot of double values in my application, is there is any easy way to handle the formatting of decimal values in Java?
Is there any other better way of doing it than
DecimalFormat df = new DecimalFormat("#.##"); What i want to do basically is format double values like
23.59004 to 23.59 35.7 to 35.70 3.0 to 3.00 9 to 9.00

What is 2.738 Round to Two Decimal Places? In the given number 2.738, the digit at the thousandths place is 8, so we will add 1 to the hundredths place digit. So, 3+1=4. Therefore, the value of 2.738 round to two decimal places is 2.74.
Just use %. 2f as the format specifier. This will make the Java printf format a double to two decimal places. /* Code example to print a double to two decimal places with Java printf */ System.
No, there is no better way.
Actually you have an error in your pattern. What you want is:
DecimalFormat df = new DecimalFormat("#.00"); Note the "00", meaning exactly two decimal places.
If you use "#.##" (# means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d); prints just "3", not "3.00".
