Write the definition of a class Clock. The class has three instance variables: One of type int called hours, another of type boolean called is Ticking, and the last one of type Integer called diff. You should also write a constructor that takes three parameters - - an int, a boolean, and another int. The constructor should set the instance variables to the values provided.

Following is the definition of class Clock:

public Clock (int hours, boolean isTicking, int diff)

{

this. hours = hours;

this. isTicking = isTicking;

this. diff = new Integer (diff);

}

Explanation:

A public class Clock has three parameters namely hours (data type: int), isTicking (data type: boolean), diff (data type: int). The class Clock contains a constructor having three parameters that are hours in int isTicking in boolean diff in integer
