Call method after closing JFrame

Question

Hi everyone,
I'm opening a JFrame in another JFrame.
Here is the code and beneath is the question.
import javax.swing.*;
import javax.swing.text.*;
import java.awt.event.*;
import java.awt.*;
import java.util.*;
public class ContactsInterface extends JFrame implements ActionListener
     JList contactList;
     private DefaultListModel listModel;
     JPanel buttonPanel;
     JPanel detailsPanel;
     JButton addButton, updateButton, deleteButton, refreshButton;
     JLabel companyLabel;
     JTextField companyField;
     public ContactsInterface()
          super("ContactList");
          listModel = new DefaultListModel();
          contactList = new JList(listModel);
          buttonPanel = new JPanel();
          detailsPanel = new JPanel();
          addButton = new JButton("Add Record");
          addButton.addActionListener(this);
          updateButton = new JButton("Update Record");
          updateButton.addActionListener(this);
          deleteButton = new JButton("Delete Record");
          deleteButton.addActionListener(this);
          refreshButton = new JButton("Refresh");
          refreshButton.addActionListener(this);
          companyLabel = new JLabel(" Company:");
          companyField = new JTextField(10);
          companyField.setEditable(false);
          buttonPanel.setLayout(new FlowLayout());
          detailsPanel.setLayout(new GridLayout(6,2,10,10));
          buttonPanel.add(addButton);
          buttonPanel.add(updateButton);
          buttonPanel.add(deleteButton);
          buttonPanel.add(refreshButton);
          detailsPanel.add(companyLabel);
          detailsPanel.add(companyField);
          setLayout(new BorderLayout());
          JScrollPane contactJScroll = new JScrollPane();
          contactJScroll.setPreferredSize(new Dimension(100,80));
          contactJScroll.getViewport().setView(contactList);
          add(contactJScroll, BorderLayout.WEST);
          add(buttonPanel, BorderLayout.SOUTH);
          add(detailsPanel, BorderLayout.CENTER);
     public void actionPerformed(ActionEvent e)
          String args = e.getActionCommand();
          if(args.equals("Add Record"))
               openAddRecord();
     public static void main(String args[])   //main method of the ContactsInterface
          ContactsInterface CInterface = new ContactsInterface();
          CInterface.setJMenuBar(CInterface.createMenuBar());
          CInterface.setDefaultCloseOperation(EXIT_ON_CLOSE);
          CInterface.setSize(500,300);
          CInterface.setVisible(true);
          CInterface.setResizable(false);
     public void openAddRecord() // The method being called when clicking Add record which in turn opens another JFrame on top of the ContactsInterface  JFrame
          record = new AddRecord();
          record.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
          record.setVisible(true);
          record.setResizable(false);
          record.setSize(400,300);
     public void refreshList(String company)  //The method that needs to be called when disposing of the openAddRecord JFrame
          listModel.addElement(company);
          int index;
          index = contactList.getLastVisibleIndex();
          index++;
          contactList.setSelectedIndex(index);
          contactList.ensureIndexIsVisible(index);
     }The "openAddRecord Frame" opens fine, in the "openAddRecord JFrame" I add a company name.
How can I when I click on the "Save" button in the "openAddRecord JFrame" and then dispose(); of the "openAddRecord JFrame" let it call a method in the "ContactsInterface JFrame" which was the parent of "openAddRecord JFrame" / were the "openAddRecord JFrame" was opened in, to refresh the JList by calling the "refreshList" method.

Don't use multiple JFrames.
A typical application will only ever have a single JFrame. If you need a second window you would use a JDialog. If you want to stop execution until the dialog is closed then you would use a "modal" JDialog.
