    {
        $this->OperatingSystem = $OperatingSystem;
        $this->ProcessorType = $ProcessorType;
        $this->HardDiskSize = $HardDiskSize;
    }

    public function getDetails()
    {
        return $this->OperatingSystem . ' - ' .$this->ProcessorType . ' - ' .$this->HardDiskSize;

$comp1 = ComputerFactory::create('Windows 10', 'Intel Core i7', '1 TB');
print_r($comp1->getDetails());

echo "<br />";

$comp1 = ComputerFactory::create('OS X Mavericks', 'Intel Core i5', '128 GB');
print_r($comp1->getDetails());
