I am creating a digital clock and I am currently trying to write a method named incrementHoursBy that implements the following specifications: /**  * Advances the entire clock by the given number of hours.   * If the hours advances past 23 they wrap around.  *   * @precondition hours >= 0  * @postcondition  the clock has moved forward   * by the appropriate number of hours  *   * @param hours the number of hours to add  */ I am not 100% sure how to do this and would appreciate some assitance. I want the method header to be public, include the above specification, return void, and have a single paramter of type int named hours. This is my code so far:      public incrementHoursBy(int hours) {         return 0;     }
