Bouton de modification en Netbeans

Bonjour toute le monde, j'ai problème avec mes boutons (modification, supprimer et recherche). Mon projet se connecte bien à la base de donnée pour afficher les informations enregistrer ou pour ajouter des information mais quand tu essaies de modifier il affiche ce message: You have an error in your SQL syntax, check the manual that corresponds to your Mysql server version for the right syntax to use near 'where id=' at line 1, pour supprimer c'est aussi:You have an error in your SQL syntax, check the manual that corresponds to your Mysql server version for the right syntax to use near 'Delet From stagaire where id=' at line 1.

Et voici mon code complet:
