Getter method must return a double - how to implement DecimalFormat?

Question

I need the getter to return a double to .2 decimal spaces...

public double getPrice () {

   double totalPrice = 0.00;
   DecimalFormat deciFormat = new DecimalFormat("#.00");

...

return Double.valueOf(deciFormat.format(totalPrice));

but when I check the result in my .jsp it's still only to 1 decimal space. Any and all insight would be greatly appreciated.

You're confusing number with a string representation of it. If the method returns a double, the string representation you create has little to do with the "significant" bits of the number returned. — Hovercraft Full Of Eels, May 26 '17 at 01:45
When i make the return type for the method a String from double now get a java.lang.NoSuchMethodError :/ — Conor Martin, May 26 '17 at 02:08
Usually, that error means you're running different code from what you've got in your source files. Maybe an earlier version of something. Make sure you rebuild everything. — Dawood ibn Kareem, May 26 '17 at 02:13
@DawoodibnKareem THANKS! did a "Clean & Build" and issue was solved! Kudos — Conor Martin, May 26 '17 at 02:20
There is no such thing as `a getter to return a double to .2 decimal spaces'. See the duplicate. — user207421, May 26 '17 at 04:14

Changed the method return type to a String. Did a "Clean and build" and String.Format did the job!

Just remember, every time you store an amount of money in a `double`, a kitten dies. – Dawood ibn Kareem May 26 '17 at 02:44
