Java Class Constructor Parameters with range limits

I'm new to Java and I'm asking this question just to help me better understand OOP.

Let's say I'm defining a new Class called Hour. To instantiate this Class, we need to specify an integer to indicate the hour of this instance.

Hour hr = new Hour(16); // this means to define an hour that indicates 4pm.

Open in new window


So when we define the Hour Class here, the parameter for the constructor should within the range [0, 24). How can we define such a parameter and can I throw an error when a parameter that is out of this range is specified?

Thanks.
