Kira kira ini error nya kenapa ya padahal saya sudah memiliki class

Parse error: syntax error, unexpected 'public' (T_PUBLIC), expecting end of file in D:\xampp\htdocs\oophp\inheritance-problem.php on line 17


class produk{
//property
public $judul,
  $penulis,
  $penerbit,
  $harga,
          $jmlhalaman,
          $waktumain,
          $tipe;
}
//constructor / method
public function __construct($judul = "judul",$penulis = "penulis",$penerbit = "penerbit",$harga = 0, $jmlhalaman = 0, $waktumain = 0,$tipe) {

    $this->judul= $judul;
    $this->penulis= $penulis;
    $this->penerbit= $penerbit;
    $this->harga= $harga;
            $this->jmlhalaman = $jmlhalaman;
            $this->waktumain = $waktumain; 

            $this->tipe = $tipe;
