Remove Currency Format - Can i parse back to a double?

[Marcus Hathaway]

Hi,

Is it possible to remove a currency format?

For instance i start with a double, e.g. 10.00.

Applying code like below will give the string �10.00.

 
Double d = 10.00
Locale uk = new Locale("en", "GB");
NumberFormat cf = NumberFormat.getCurrencyInstance(uk);
String s = cf.format(d);   

However, i now want to be able to convert that string back to its double value. Anyone know how i can do this?

Also, its not possible for me to use the original double!

Any advice would be greatly appreciated!

Cheers

This isn't a swing-specific question, so I'm moving it to JiG intermediate.

Try this:

import java.text.NumberFormat;
import java.util.Locale;
import java.text.ParseException;
public class NumberFormatTest
{
   public static void main(String[] args)
   {
      double d = 10.00;
      Locale uk = new Locale("en", "GB");
      NumberFormat cf = NumberFormat.getCurrencyInstance(uk);
      String s = cf.format(d);
 
      System.out.println(s);
 
      Number number = null;
      try
      {
         number = cf.parse(s);
      }
      catch (ParseException e)
      {
         System.out.print(e);
      }
      double dClone = number.doubleValue();
      System.out.println(dClone);
   }
}    

Hope it helps. Just a note, the parse(String) method will return a long if possible so for your original example it will return a long with a value of 10. Therefore to insure that the final value is a double you must invoke the doubleValue() method.
