[after §7.6] In the following Time and TimeDriver class skeletons, replace the italicized <insert . . . > lines with your own code such that the program operates properly. More specifically:
a) In the Time class, provide a method definition for the setHours method such that setHours can be called as part of a method-call chain.
b) In the TimeDriver class, provide a single statement that chains calls to the setHours, set- Minutes, setSeconds, and printTime methods. Use reasonable values for your method-call arguments. If you pass 8 to setHours, 59 to setMinutes, and 0 to setSeconds, then your method-call-chaining statement should print this:
08:59:00
public class Time
private int hours;
private int minutes;
{
private int seconds;
