       public static void main(String[] args)
           throws Exception
       {
   
           // Get the percent instance
           NumberFormat nF
               = NumberFormat.getPercentInstance();
   
           // Sets the currency to Canadian Dollar
           nF.setCurrency(Currency
                              .getInstance(

           // Stores the values
           String values
               = nF.getCurrency()
                     .getDisplayName();
   
           // Prints the currency
           System.out.println(values);
       }
   }
   Output:

       {
   
           // Get the percent instance
           NumberFormat nF
               = NumberFormat
                     .getPercentInstance();
   
           // Stores the values
           String values
               = nF.getCurrency()
                     .getDisplayName();
   
           // Prints the currency
