I am having problems with getting my panels to work using Java?

Question

Code:

class bVendorListener implements ActionListener

{

public void actionPerformed(ActionEvent e) //when the vendor button is clicked

{

JPanel vendorPanel = JPanel();

vendorPanel.setLayout(new BoxLayout(vendorPanel, BoxLayout.PAGE_AXIS));

}

private vendorPanel()

{

Label vendorNameLabel = new Label("Vendor Name");

TextField vNameField = new TextField();

Label vendorAddLabel = new Label("Vendor Address");

TextField vAddField = new TextField();

Label vendorCityLabel = new Label("Vendor City");

TextField vCityField = new TextField();

Label vendorStateLabel = new Label("Vendor State");

TextField vStateField = new TextField();

Label vendorZipLabel = new Label("Vendor Zip");

TextField vZipField = new TextField();

Label vendorPhoneLabel = new Label("Vendor Phone");

TextField vPhoneField = new TextField();

Label vendorContactLabel = new Label("Vendor Contact");

TextField vContactField = new TextField();

Label vendorProductLabel = new Label("Vendor Product");

TextField vProductField = new TextField();

}

}

Error:
