Challenge 1 / 2

Check out the following code:

class Ship
{
    private $weaponsCount = 5;

    public function getWeaponsCount()
    {
        return $this->weaponsCount;
    }
}

class RebelShip extends Ship
{
    public function getWeaponsCount()
    {
        return parent::getWeaponsCount() + 2;
    }
}

$rebelShip = new RebelShip();
print $rebelShip->getWeaponsCount();

How many weapons will the getWeaponsCount() call return for the $rebelShip?

It will throw an error because we cannot call the getWeaponsCount() method via parent:: from inside of the RebelShip.

This will cause an error because $weaponsCount is private in Ship, so it can't be accessed in RebelShip.
