I am trying to append a "$" in front of my number, but for some reason it isn't being added.

Here is a code snippet:

 
// Round the number to two decimal places, then format it properly.
    public String roundTwoDecimals(double number) {
    	DecimalFormat twoDecForm = new DecimalFormat("$0.00");
    	String dollarAmount = twoDecForm.format(number);
    	return dollarAmount;
    }

check this:

        DecimalFormat fff = new DecimalFormat("$#####.00");
        System.out.println(fff.format(345.6789));

               System.out.println(fff.format(365.0));

        System.out.println(fff.format(365));

Open in new window


Output:
$345.68
$365.00
$365.00

It still isn't adding the $ sign.

I'm wondering if it might be something in my Eclipse environment that isn't allowing it to show.

   public static String roundTwoDecimals(double number) {
    	DecimalFormat twoDecForm = new DecimalFormat("$0.00");
    	String dollarAmount = twoDecForm.format(number);
    	return dollarAmount;
    }

    public static void main(String[] args) {

                  System.out.println("  output: " + roundTwoDecimals(365));

}
}

That  would be really strange

If you just do

System.out.println("$256.00")

does it print dollar sign ?
