这是我一直在使用的代码：
submit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
info.setBillingStreet(billingStreetAddressTextField.getText()); //This is to test the Edit menu item from the BookOrder class
System.out.print(billingStreetAddressTextField.getText());
info.setQuantityPurchase(quantityPurchaseTextField.getText());
info.setCurrentInventory(Integer.parseInt(quantityPurchaseTextField.getText()));
int n = info.getCurrentInventory(); //UPDATED VALUE
inventory.createInventoryDetailsPanel(n);//PASSING THE UPDATED VALUE TO THE INVENTORY CLASS
}
});
import java.awt.FlowLayout;
import javax.swing.BoxLayout;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;
import javax.swing.JTextField;
public class Inventory extends JPanel {
private JTabbedPane pane = null;
final JTextField inventoryTextField = new JTextField();
OrderInfo info2 = new OrderInfo();
JPanel mainPanel = new JPanel();
JPanel panel2;
JPanel panel22;
int currentInventory = 5000;
int n;
public Inventory() {
JPanel componentsPanel = new JPanel();
componentsPanel.setLayout(new BoxLayout(componentsPanel,
BoxLayout.PAGE_AXIS));
componentsPanel.add(createInventoryPanel());
add(mainPanel);
mainPanel.setVisible(true);
mainPanel.add(componentsPanel);
add(mainPanel);
}
public JTabbedPane createInventoryPanel() {
pane = new JTabbedPane();
pane.addTab("Inventory Details", createInventoryDetailsPanel(n));
pane.addTab("Inventory Reordering", createInventoryOrderingPanel());
return pane;
}
JPanel createInventoryDetailsPanel(int n) {
panel22 = new JPanel();
mainPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
JPanel panel1 = new JPanel();
panel2 = new JPanel();
panel1.setLayout(new BoxLayout(panel1, BoxLayout.Y_AXIS));
panel2.setLayout(new BoxLayout(panel2, BoxLayout.Y_AXIS));
panel1.add(new JLabel("Item", JLabel.CENTER));
panel1.add(new JLabel(" Java How To Program : Deitel and Deitel "));
panel2.add(new JLabel("Quantity", JLabel.CENTER));
panel2.add(inventoryTextField);
System.out.print("Current Inventory is " + n);
if (n != 0) {//THIS IS WHERE I'M HAVING PROBLEMS TRYING TO PASS THE BEAN from the New Order class
//SO THE NEW VALUE WILL SHOW IN THE TEXT FIELD FOR INVENTORY DETAILS.
//IT ALWAYS SHOWS 5000 NO MATTER WHAT (INITIALIZED ABOVE)
inventoryTextField.setText(String.valueOf(n));
} else {
inventoryTextField.setText(String.valueOf(currentInventory));
}
panel22.add(panel1);
panel22.add(panel2);
return panel22;
}

return panel;
}
}
