Store and Retrieve Problem.

I've written a program and i need to implement some features.
These features are on another program that i was given as an example.I've attached the program into this thread.
In the program attached there's a save,clear,showall, and showcurrent buttons. I'd like to have the same feature. I've already made the buttons for my program but i cant think of the code to make them do what they do on IDEWindow03. I know i have to make an arraylist to store the data but i cant figure out where to make this. Here's my code for my program.

Code:

Is it possible to replicate the IDEWindow03 code to my program?
thanks in advance.

tl;dr

kind regards,

Jos

Anyone else?

In short i'm trying to Implement this code from IDEWindow03.

Code:

---

private void saveActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_saveActionPerformed
// TODO add your handling code here:
        if(evt.getActionCommand().equals("Save")) {
            updatePerson(); //retrieve contents of window and store in person
            personList.add(person);  //always appending
        }

---

Into my Program, I'm guessing it would go somewhere here

Code:

---

  private class OptionButtonPanel extends JPanel {
      public OptionButtonPanel() {
          setLayout(new FlowLayout());
          OptionButtonListener optionButtonListener =
                  new OptionButtonListener();
          JButton displayButton = new JButton("Show Current");
          add(displayButton);
          displayButton.addActionListener(optionButtonListener);
          JButton saveButton = new JButton ("Save");
          add (saveButton);
          saveButton.addActionListener(optionButtonListener);
          JButton showButton = new JButton ("Show All");
          add(showButton);
          showButton.addActionListener(optionButtonListener);
          JButton clearButton = new JButton ("Clear");
          add (clearButton);
          clearButton.addActionListener(optionButtonListener);
          JButton quitButton = new JButton("Exit");
          add(quitButton);
          quitButton.addActionListener(optionButtonListener);
      }
  }

  private class OptionButtonListener implements ActionListener {
    public void actionPerformed(ActionEvent event) {
      String command = event.getActionCommand();
      if(command.equals("Show Current")) {
          // assign data extracted from window to person object
          person.setForename(firstNameField.getText());
          person.setSurname(surnameField.getText());
          person.setAccountnumber (accountNumberField.getText());
          person.setDOB(date, month, year);
          // extract data from person object and write to text area
          dataArea.append("Forename: ");
          dataArea.append(person.getForename());
          dataArea.append(" Surname: ");
          dataArea.append(person.getSurname());
          dataArea.append ("\n Account Number: ");
          dataArea.append(person.getAccountnumber());
          dataArea.append("\nAcc. Start Date: ");
          dataArea.append(Integer.toString(person.getDateOfBirth()) + '/' +
                      Integer.toString(person.getMonthOfBirth()) + '/' +
                      Integer.toString(person.getYearOfBirth()));
          dataArea.append("\nAge of Account: " + Integer.toString(person.getAge()));
          dataArea.append ("\nBank: ");
          dataArea.append(bank);
          dataArea.append("\n"); // new line
      }
      if(command.equals("Exit")) {
          int option = JOptionPane.showConfirmDialog(null, "Do you really want to exit?",
                              "Confirm", JOptionPane.YES_NO_OPTION);
            if(option == JOptionPane.YES_OPTION) {
                System.exit(0);
            }

        }
      }

I've already created the save button i just need it to "save". How would i do this?

Why not put the following code fragment:

Code:

---

if(evt.getActionCommand().equals("Save")) {
            updatePerson(); //retrieve contents of window and store in person
            personList.add(person);  //always appending
        }

---

... in the actionPerformed( ... ) method of your OptionButtonListener class?
Unless I'm missing something completely that should do it.

kind regards,

JOs

I tried that it gives me an error on personlist
and updateperson. I understand i need to create an arraylist first to identify personlist? where would i put this?
Because i copied the array list from the IDEwinow code but that didnt work it gave me an error too.
