could someone confirm if this is the correct way to hook up custom logic to document handlers in v4.10

public class SetDefaultsHandler : IApplicationEventHandler
    {

        public void OnApplicationInitialized(UmbracoApplication httpApplication, ApplicationContext applicationContext)
        {
            //your code here
        }

        public void OnApplicationStarting(UmbracoApplication httpApplication, ApplicationContext applicationContext)
        {
            //your code here
        }

        public void OnApplicationStarted(UmbracoApplication httpApplication, ApplicationContext applicationContext)
        {
            //your code here
        }


        public SetDefaultsHandler()
        {
            Document.New += new Document.NewEventHandler(Document_New);
        }

        void Document_New(Document sender, umbraco.cms.businesslogic.NewEventArgs e)
        {
    //CODE HERE
    }
}
