Czyszczenie wektora

Witam
Mam taki problem, że gdy czyszczę wektor to otrzymuję błąd

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0 >= 0

Oto mój kawałek kodu:

	public void updateProductList()
	{
		Vector<String> v = new Vector<>();
		//DefaultTableModel model;
		Statement stat;
		String id;
		String name;
		String price;
		String plu;
		String code;
		String tax;
		String amount;

		try
		{
			stat = conn.createStatement();
			ResultSet rs = stat.executeQuery("select * from Products;");
			while (rs.next())
			{
				id = rs.getString(1);
				v.addElement(id);
				name = rs.getString(2);
				v.addElement(name);
				price = rs.getString(3);
				v.addElement(price);
				plu = rs.getString(4);
				v.addElement(plu);
				code = rs.getString(5);
				v.addElement(code);
				tax = rs.getString(6);
				v.addElement(tax);
				amount = rs.getString(7);
				v.addElement(amount);

				model.addRow(v);
				v.clear();
			}
			rs.close();
			stat.close();
		}
		catch (SQLException e)
		{
			e.printStackTrace();
		}
	}

Gdzie model jest modelem obiektu JTable. W każdym razie instrukcja v.clear() powoduje wystąpienie błędu. Proszę o podpowiedź czemu tak się dzieje.

Nie podoba mi się Twój pomysł z czyszczeniem wektora, który jest już umieszczony w modelu. Ja bym zrobił tak:

                        while (rs.next())
                        {
                                Vecor<String> v = new Vector<String>();
                                id = rs.getString(1);
                                v.addElement(id);
                                name = rs.getString(2);
                                v.addElement(name);
                                price = rs.getString(3);
                                v.addElement(price);
                                plu = rs.getString(4);
                                v.addElement(plu);
                                code = rs.getString(5);
                                v.addElement(code);
                                tax = rs.getString(6);
                                v.addElement(tax);
                                amount = rs.getString(7);
                                v.addElement(amount);
 
                                model.addRow(v);
                        }

Rozważałem takie podejście tylko nie rozumiem, czemu nie mogę zrobić tak jak w moim kodzie.

Bo w każdym wierszu modelu masz tę samą referencję. Nawet jak nie będzie błędu, to wyświetlisz identyczne wiersze (z ostatnim odczytanym rekordem).

OK już chyba rozumiem. Dzięki
