How can I print a double value 0.0 to 0.00?

Hi

I am trying to print a string value to Double .But i need to print in different format..

I have used the following code

String s1 = "2"
String s2 = ".1"
Double d1 = new Double(s1);
Double d2 = new Double(s2);
System.out.println("First double"+d1+"### Second double "+d2);

Its pirnting
FirstDouble 2 ### Second double 0.1.

But i want it be printed as
d1 as 2.00 and d2 as 0.10

How can it be possible?

Thanks.
Vijaya.

NumberFormat nf = new DecimalFormat("0.00");
s1 = nf.format(d1.doubleValue());

I am getting the output,but it is as string but i need it as Double.

DecimalFormat df = new DecimalFormat("0.00");
FieldPosition fp = new FieldPosition (NumberFormat.INTEGER_FIELD);
StringBuffer sb= new StringBuffer();
sb = df.format( d1 , sb, fp );

then its printing sb as 2.00

But i need it to be as Double that's why i coverted this to string and parsed..as

Double dd = new Double(sb.toString());

then its printing,same 2 again...what should i do,if i want to print 2.00 as Double object.

thanks.

The representation of an object, when materialized as a String, has a varying relation to its binary content. In the case of numbers, or object wrappers of numbers, the binary form is, and should be, distinct and different
