formatting number

[mank]

I have to write a method which is supposed to do the following -

When input is 2.00, it converts to $2
When input is 2.01, it converts to $2.01
When input is 2, it converts to $2

Is there any utility method in java which can do that?

Yes, you can use class DecimalFormat to do it. Because this is very likely a
homework assignment, if you will post your code, someone here will help you
get it working.

This question is much more suited to comp.lang.java.help.
As Paul said, post the code you have so far, and what it's doing wrong.
