Please forgive me if I did not code my program correctly. If you could let me know if I did it right or not I would greatly appreciate it.

I am able to complie my program, but I get run errors that state the following:

Exception in thread "main" java.util.UnknownFormatConversionException: Conversion = '.'

I know I am doing something strangely wrong, but can not figure it out.

Is this the correct way?

>System.out.printf(inventory[counter].toString());

I do not think there is any function like printf in Java. It should be either print or println.

>System.out.printf( "The total value of the inventory is $%.2f\n\n", total );

Same as above.

>formatString += "Units: $%.d\n";

should be

formatString          += "Units: $%d\n";

I think this will remove the following errors:

at CD.toString(InventoryPart3.java:166)
at InventoryPart3.main(InventoryPart3.java:35)

Try compiling it after the above stated changes.

As error say there is problem with line 166 which is part of your method toString

public String toString ()       
   {
      String formatString    = "Name: %s\n";
      formatString          += "Artist: %s\n";
      formatString          += "Number: %d\n";
      formatString          += "Units: $%.d\n";
      formatString	   		+= "Price:$%.2f\n";
      formatString          += "Value: $%.2f\n\n";
      
      return (String.format ( formatString, NameIn, ArtistIn, NumberIn, UnitsIn, PriceIn, getValue()) ); 
         
   } // End toString method

You calling variables that are return by get methods instead of calling methods to get this variables

>System.out.printf(inventory[counter].toString());

I do not think there is any function like printf in Java. It should be either print or println.

As of 1.5, yes there is, but it is not used in this manner. You need to pass it an optional locale object, a format pattern string, and an array of objects to match the arguments in the pattern string.

You calling variables that are return by get methods instead of calling methods to get this variables

Ah! I didn't notice this error while inspecting the program for the first time. I really need to keep my eyes wide open.

Ah! I didn't notice this error while inspecting the program for the first time. I really need to keep my eyes wide open.

I do not know how to fix this error..I see the line

return (String.format ( formatString, NameIn, ArtistIn, NumberIn, UnitsIn, PriceIn, getValue()) );


Does it make sense to format a String for all the variable? And how do I call on the variables?

Ok. I was not aware of that. Thank You!

it's not used much. It's been available for like 4 years now, I use Java 1.5 professionally on a daily basis, and I've never encountered it outside web articles listing the new features of 1.5.
Even most books dealing specifically with 1.5 (and were written after it hit the street) don't so much as mention it.

One of the less successful things Sun did to Java before 1.6.

Yup, perhaps that is the reason I had never heard about it before ;)

I didn't insist you to do that.

And how do I call on the variables?

Inside the return(String.format()), use the get methods that you have defined for each data field to refer to data like NameIn, ArtistIn, NumberIn... etc.

/* Hi i corrected some codes in your program .. compile and run the program.. i didnt correct your Artist class.. because you didnt use in your program.... You are using most of the C language syntax thats why so much error... */.. Chech and tell ...

If you made any correction to the code it would be helpfull if you highlighted (display in different colour).
PS: Please use code tag for whole supplied code not for section. The tag is to keep original aligment not to break it down how you did.
