Creating Class

[puneet]

Write a  class for feeding a horse. The Horse object should keep track of the last time it was fed and calculate when it is hungry. Assume there is another class that checks the horse every 10 minutes to see if it is hungry and if it is, it calls another method which feeds it. There should be about 3 methods on the class, but more can be added if needed. 

 

It's was question in my exam which I skipped

 

Can somebody hep me with that Please

class Horse
{
     private fedtime;

     public function __construct()
     {
          $this->fedtime = new DateTime('yesterday');
     }

     public function getLastFedTime()
     {
          return $this->fedtime;
     }

     public function setLastFedTime($time)
          $this->fedtime = $time;
     }

     public function isHungry()
     {
          $now = new DateTime();
          $interval = date_diff($this->fedtime, $now);
          
          return $interval->format('%a') > 1; // gives true if the fedtime is more then one day ago, otherwise false.
     }

}
 

And now you do the rest!

class Horse

{

  public function __construct(DateTime $lastFedAt) {

    $this->lastFedAt = $lastFedAt;

  }


  public function feed() {

    $this->lastFedAt = new DateTime();

  }


  public function isHungry() {

    if (date('H') < 6 || date('H') > 22) {

      return false; // sleeping

    }

    return time() - $this->lastFedAt->getTimestamp() > 4 * 3600; // feed every 4 hours

  }

}


class HorseFeeder

{

  public function check(Horse $horse) {

    $horse->isHungry() && $horse->feed();

  }


  public function checkLoop(Horse $horse) {

    while (true) {

      $this->check($horse);

      sleep(600);

    }

}

You skipped a class, a test no less, and you want someone here to write your answer for you.  SHAME ON YOU AND SHAME ON ANYONE HERE WHO GIVES YOU WHAT YOU ASK FOR.

He skipped the question on the test, probably couldn't answer it. Probably just trying to see what the answer was that was on the test.

Then he should get a solution from the teacher or from the other students so that he gets something appropriate for the context of his course.
