user roles in laravel

i am trying to give roles to the users .i tried working with packages but wasn't successful so i was following a youtube video,everything went fine until i tried to seed the databse. [ReflectionException]
Class RoleTableSeeder does not exist when i was trying a package entrust,i was facing a similar problem. `

my DatabaseSeeder file is

` <?php `

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder { /** * Run the database seeds. * * @return void */ public function run() { $this->call(RoleTableSeeder::class); $this->call(UserTableSeeder::class); } } my UserTableSeeder file is `

use Illuminate\Database\Seeder; use App\User; use App\Role;

class UserTableSeeder extends Seeder { /** * Run the database seeds. * * @return void */ public function run() { $role_user = Role::where('name', 'User')->first(); $role_author = Role::where('name', 'Author')->first(); $role_admin = Role::where('name', 'Admin')->first();

    $user = new User();
    $user->first_name = 'Victor';
    $user->last_name = 'Visitor';
    $user->email = 'visitor@example.com';
    $user->password = bcrypt('visitor');
    $user->save();
    $user->roles()->attach($role_user);

    $admin = new User();
    $admin->first_name = 'Alex';
    $admin->last_name = 'Admin';
    $admin->email = 'admin@example.com';
    $admin->password = bcrypt('admin');
    $admin->save();
    $admin->roles()->attach($role_admin);

    $author = new User();
    $author->first_name = 'Andy';
    $author->last_name = 'Author';
    $author->email = 'author@example.com';
    $author->password = bcrypt('author');
    $author->save();
    $author->roles()->attach($role_author);
}

} `

my RoleTableeSeeder file is `

use Illuminate\Database\Seeder; use App\Role;

class RoleTableSeeder extends Seeder { /** * Run the database seeds. * * @return void */ public function run() { $role_user = new Role(); $role_user->name = 'User'; $role_user->description = 'A normal User'; $role_user->save();

    $role_author = new Role();
    $role_author->name = 'Author';
    $role_author->description = 'An Author';
    $role_author->save();

    $role_admin = new Role();
    $role_admin->name = 'Admin';
    $role_admin->description = 'A Admin';
    $role_admin->save();
}

} `
