Java - Insercion en BBDD mysql

Buenas tengo el siguiente codigo para insertar en una BBDD mySql

Statement stm = null;
String sql = null;
int rs ;

try {
stm = (Statement) conexion.getConexion().createStatement();
} catch (SQLException ex) {
Logger.getLogger(F_AltaSocio.class.getName()).log(Level.SEVERE, null, ex);
}

sql = "Insert into socio (dni, nombre, apellidos, nHermano, direccion, telefonono, movil, correoElectronico) values ("
+ nuevo_socio.dni + ","
+ nuevo_socio.nombre + ","
+ nuevo_socio.apellidos + ","
+ nuevo_socio.nhermano + ","
+ nuevo_socio.direccion + ","
+ nuevo_socio.telefono + ","
+ nuevo_socio.movil + ","
+ nuevo_socio.correoElectronico + ")";

System.out.println(sql);

try {
rs=stm.executeUpdate(sql);

} catch (SQLException ex) {
Logger.getLogger(F_AltaSocio.class.getName()).log(Level.SEVERE, null, ex);
}
