public class CarInventoryReport
{
   public static void main(String[] args)
   {
      final String HEADING_FMT_STR = "%-25s%13s%13s%13s\n";
      final String DATA_FMT_STR =  "%-25s%13d%13.0f%13.0f\n";
      String item1 = "Mazda RX-8";
      int qty1 = 10;
      double price1 = 27999.99;
      String item2 = "MINI Cooper";
      int qty2 = 100;
      double price2 = 23000.25;

      System.out.printf(HEADING_FMT_STR,
         "Item", "Quantity", "Price", "Value");
      System.out.printf(HEADING_FMT_STR,
         "-----", "-------", "------", "------");
      System.out.printf(DATA_FMT_STR,item1,qty1,price1,qty1*price1);
      System.out.printf(DATA_FMT_STR,item2,qty2,price2,qty2*price2);
  } // end main
} // end class CarInventoryReport
public class C
