Write the definition of a class Clock. The class has three instance variables: One of type int called hours, another of type boolean called isTicking, 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.

Step-by-step explanation:

The definition of class as per given information is written below;

public class Clock

{

private int hours;

private boolean isTicking;

private Integer diff;

}

The constructor that takes the three variables and then set the values to the instance variables is;

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

{

this.hours = hours;

this.isTicking = isTicking;

this.diff = new Integer (diff);

}
