Iam trying to position my jlabel in a jpanel what is made final because of an actionlistener.

final JPanel panelPayDetails = new JPanel();
panelPayDetails.setBounds(250, 25, 350, 250);

JLabel lblnumber = new JLabel("Insert Number:");         
lblnumber.setFont(Applicatie.FONT_12_BOLD);
lblnumber.setBounds(5, 5, 200, 20);

panelPayDetails.add(lblnumber);
panelPayDetails.setVisible(false);
jpExtraDetails.add(panelPayDetails);

bill.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e)
            {                
              if(bill.getSelectedItem() == "CREDIT CARD")
              {

                   panelPayDetails.setVisible(true);
              }
            }
        });

im not luck so far.. because the label is positioned in the middle of the jpanel.. how come?

因为 JPanel 的默认布局管理器是 FlowLayout，它使事物居中。阅读本教程。
