Write a Java program with a class named Clock for dealing with the time represented by hours,

minutes, and seconds. Your class must have the following features:

$$ Three instance variables for the hours $($range $0-23),$ minutes $($range $0-59),$ and seconds

$($range $0-59).$

$$ Three Constructors:

o Default $($with no parameters passed; is should initialize the represented time to

$12$:$00$:$00)$

o a constructor with three parameters: hours, minutes, and seconds.

o a constructor with one parameter: the value of time in seconds since midnight $($it

should be converted into the time value in hours, minutes, and seconds$)$

$$ Instance Methods:

o a set$-$method method setClock$()$ with one parameter seconds since midnight $($to be

converted into the time value in hours, minutes, and seconds as above$).$

o get$-$methods getHours$(),$ getMinutes$(),$ getSeconds$()$ with no parameters that

return the corresponding values.

o set$-$methods setHours$(),$ setMinutes$(),$ setSeconds$()$ with one parameter each that

set up the corresponding instance variables.

o method tick$()$ with no parameters that increments the time stored in a Clock object

by one second.

o method addClock$()$ accepting an object of type Clock as a parameter. The method

should add the time represented by the parameter class to the time represented in

the current class.

o Add an instance method toPrint$()$ with no parameters to your class. toPrint$()$ must

return a String representation of the Clock object in the form $"($hh:mm:ss$)",$ for

example $"(03$:$02$:$34)".$

o Add an instance method tickDown$()$ which decrements the time stored in a Clock

object by one second.

o Add an instance method subtractClock$()$ that takes one Clock parameter and

returns the difference between the time represented in the current Clock object

and the one represented by the Clock parameter. Difference of time should be

returned as a clock object.

Write a separate class named ClockDemo with a main$()$ method. The program should:

$$ Instantiate a Clock object firstClock using one integer seconds since midnight obtained

from the keyboard.

$$ Tick the clock ten times by applying its tick$()$ method and print out the time after each

tick.

$$ Extend your code by appending to it instructions instantiating a Clock object

secondClock by using three integers $($hours$,$ minutes, seconds$)$ read from the keyboard.

$$ Then tick the clock ten times, printing the time after each tick.

$$ Add the secondClock time in firstClock by calling method addClock.

$$ Print both clock objects calling toPrint$()$ method.

$$ Create a reference thirdClock that should reference to object of difference of firstClock

and secondClock by calling the method subtractClock$().$
