public void inserirContato(){   
    try{       
        String SQL = "INSERT INTO contatos (Cod_Contato, Nome_Contato,Email_Contato,Aniv_Contato,Idade_Contato,Tel1_Contato,Tel2_Contato,Obs_Contato) Values ('" +

        if(ex.getMessage().equals("General error"))

        else   
            JOptionPane.showMessageDialog(null, "Data inválida");   
    }   
}   
public void actionPerformed(ActionEvent e) {   
    if(e.getSource() == contCadastrar){   
        inserirContato();   
    }   
}

Mas ainda dá o seguinte erro…
