How to get the hour to restart on a clockTower once it reaches a certain value

When I run my program the hour does not restart back to zero instead it keeps going.

For example if Tower A is at 0 and Tower B is at 23 and I want to add 8 hours

My code outputs:
Tower A is at 9 and Tower B is at 32.

public void advanceClock(int numHours)

{

    if (hour >= 0 && hour <= 23)

    {
    hour = hour + numHours;
    advanceOneHour();
    }   
}

This is what the instance method should do:

public void advanceClock (int numHours)

Advances the current hour on this ClockTower by numHours hours. The hour will always be between 0 (midnight) and 23 (i.e., the next hour after 23 is 0).

Expected output is:
Tower A is at 8 and Tower B is at 7.

create a reset() method and call that – Stultuske Jan 23 '19 at 10:54
Even if i reset the value how do i get it to keep adding the correct amount. The leftover value of numHours from before the value needed to get reset – Maribel Bautista Jan 23 '19 at 11:03

`hour = (hour + numHours) % 24` should do the trick. – Federico klez Culloca Jan 23 '19 at 11:05

you can create an advance method that adds only one hour, and call it the x times you are passed as hours. that way, all you need to do is: if ( time == 23.00 ) time = 0.00; else time +1 hour – Stultuske Jan 23 '19 at 11:05
Even when I try hour = (hour + numHours) % 24 my output comes out to Tower A is at 9 and Tower B is at 8. – Maribel Bautista Jan 23 '19 at 11:13

That's because you then call `advanceOneHour()`, I suppose – Federico klez Culloca Jan 23 '19 at 11:20
