Bonjour,

1)
    private Object dtgrid;
    private final Object grp;
    
    /** Creates new form start */
    public start() {
        initComponents();
        grp.add(jRadioButton1);
         grp.add(jRadioButton2);
    }
public void afficher(){
  dtgrid.setModel(stg.gettruks());
}

grp
ne devrait pas être de type Object, vu son utilisation c'est un java.awt.Container. De plus comme il est déclaré final il doit obligatoirement être instancié par le constructeur.

Idem pour dtgrid, ce n'est pas un Object mais un javax.swing.JTable

2)
private void formWindowClosed(java.awt.event.WindowEvent evt) {                                  
mybd.disconnect();
}

Tu dois déclarer et initialiser un attribut mybd si tu veux l'utiliser. Sinon il faut supprimer son utilisation.

3) Remarque : ton code dépend de la classe stagiaire, si elle est mal faite cela peut entraîner des erreurs de compilation supplémentaire.

Voici le minimum à avoir pour compiler la classe start : 
public class stagiaire {
    public ResultSet rset;
    public TableModel gettruks() {
        return null;
    }
    public void ajouter(String text, String text2, double m, String d) {
    }
    public void modifier(int mat, String text, String text2, double m, String text3) {        
    }
    public void supprimer(int mat) {        
    }
    public ResultSet recherchenom(String text) {
        return null;
    }
    public ResultSet recherchemat(int mat) {
        return null;
    }
}

mercii pour votre reponse voila ma classe stagiaire je crois pas y a un probleme mais le probleme dans l autre classe j ai bien saisi ce que vous avez di mais je sais pa encore qu est ce que je dois modifier et enlever

package gestagiaires;


import java.sql.*;
import javax.swing.table.*;
import javax.swing.JOptionPane;

public class stagiaire {
public Statement stx;
public String query;
public ResultSet rset;

public Connection cn;
JOptionPane jop1, jop2, jop3;
public stagiaire(){
mybd.connect();
cn = mybd.getConn();
}
public void ajouter(String nom,String prenom,double moy,String date){
try {
query="INSERT INTO stg VALUES ('"+nom+"', '"+prenom+"', "+moy+", '"+date+"')";
stx = cn.createStatement();
int rs = stx.executeUpdate(query); cn.commit();

} catch (SQLException ex) {

}

}
public void modifier(int mat,String nom,String prenom,double moy,String date){
try {
query="UPDATE stg SET nom='"+nom+"',prenom='"+prenom+"',moyenne="+moy+",daten='"+date+"' WHERE mat="+mat+"";
stx = cn.createStatement();
int rs = stx.executeUpdate(query); cn.commit();

} catch (SQLException ex) {

}
}
public void supprimer(int mat){
try {


query="DELETE FROM stg WHERE mat = "+mat+"";
stx = cn.createStatement();
int rs = stx.executeUpdate(query);
cn.commit();

}catch (SQLException ex) {
}


}
public ResultSet recherchemat(int mat){

try {
//Execution de la requete
query="SELECT * FROM stg WHERE mat = "+mat+"";
stx = cn.createStatement();
rset = stx.executeQuery(query); cn.commit();
rset.next();
} catch (SQLException ex) {

}
return rset;
}
public DefaultTableModel gettruks(){
DefaultTableModel dt = new DefaultTableModel();
dt.addColumn("Mat");
dt.addColumn("Nom");
dt.addColumn("Prenom");
dt.addColumn("Moyenne");
dt.addColumn("Date");
try {
query="SELECT * FROM stg ";
stx = cn.createStatement();
rset = stx.executeQuery(query); cn.commit();
while(rset.next()){
Object [] st = {rset.getInt(1),rset.getString(2),rset.getString(3),rset.getString(4),rset.getString(5)};
dt.addRow(st);
}

} catch (SQLException ex) {

}
return dt;
}

ResultSet recherchenom(String text) {
throw new UnsupportedOperationException("Not yet implemented");
}

}

"j ai bien saisi ce que vous avez di mais je sais pa encore qu est ce que je dois modifier et enlever"
Si tu as compris ce que j'ai dit où est la difficulté à trouver comment modifier ?
Je t'ai tout indiqué !!!

1) Tu remplaces ça : 
    private Object dtgrid;
    private final Object grp;

Par ça : 
    private JTable dtgrid;
    private final Container grp = new Container();

2) Tu ajoutes (je ne sais pas quoi, mais ça doit être dans tes classes) 
    private ???? mydb;
