Challenge 1 / 1

Check out the following code:

// Ship.php

class Ship
{
    public $name;

    protected $weaponPower;

    private $defense;

    public function getDefense()
    {
        return $this->defense;
    }
}

// JediShip.php

class JediShip extends Ship
{
    public function getWeaponPower()
    {
        return $this->weaponPower;
    }
}

// index.php

$jediShip = new JediShip();
$jediShip->name;
$jediShip->weaponPower;

Which of the above code will give us an error?

$jediShip->weaponPower in index.php

return $this->defense in Ship.php

return $this->weaponPower in JediShip.php

None of the above is bad code - we're awesome!
