How to fix Class 'app\hotelroom' not found error in laravel?

Im new to laravel , i have created migration and the table (hotelroom) earlier but forgot to create the model for the same ,bu now after creating the model and trying to retrieve the data , im getting above error

This is where it highlights the error

namespace App\Http\Controllers; 

use Illuminate\Http\Request;
use app\hotelroom;
class manage_roomscontroller extends Controller
{
   public function __construct()
   {
       $this->middleware('auth');
   }
   public function index()
   {
       $arr['hotelrooms']=hotelroom::all();
       return view('admin.rooms.index')->with($arr);
   }
}

Arguments
"Class 'app\hotelroom' not found" 
``````````````````````````````````

model ( located under app directory)

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class hotelroom extends Model
{

}

can someone tell me where the issue is? is it because i have created the model later ?( not at the same time while I created the migration). or its some other issue?
