Absolutely. You can see the difference it makes for yourself.

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

As error say there is problem with line 166 which is part of your method toString
You calling variables that are return by get methods instead of calling methods to get this variables
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 Learn to see in another's calamity the ills which you should avoid.

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.
