42,016 Pointsyou have a few things wrong with your code:
first you named your GoKart object String. that is a bad idea since String is a class in java already so whenever you reference your GoKart called String it probably thinks you mean the String class. name it something else like goKart:
GoKart goKart = new GoKart ("red");
then in your printf you used %n as the format specifier instead of %s. you need to use %s because getColor returns a string, and %s is the format specifier for strings. remember to reference the new name of the GoKart, goKart
GoKart goKart = new GoKart ("red");
System.out.printf("The GoKart is %s", goKart.getColor());
below is a table of common format specifiers obtained from this page
<table> <tbody> <tr> <td>%c</td> <td>character</td> </tr> <tr> <td>%d</td> <td>decimal (integer) number (base 10)</td> </tr> <tr> <td>%e</td> <td>exponential floating-point number</td> </tr> <tr> <td>%f</td> <td>floating-point number</td> </tr> <tr> <td>%i</td> <td>integer (base 10)</td> </tr> <tr> <td>%o</td> <td>octal number (base 8)</td> </tr> <tr> <td>%s</td> <td>a string of characters</td> </tr> <tr> <td>%u</td> <td>unsigned decimal (integer) number</td> </tr> <tr> <td>%x</td> <td>number in hexadecimal (base 16)</td> </tr> <tr> <td>%%</td> <td>print a percent sign</td> </tr> <tr> <td>\%</td> <td>print a percent sign</td> </tr> </tbody> </table>
