Store Jtextfield input in Arraylist then print contents of Arraylist

Question

This is my first time creating a GUI. I can create text fields just fine, but am having trouble collecting user input and storing their input into an Arraylist.

import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import javax.swing.JTextField;

textField1 = new JTextField("Enter resident name",20); 
  add(textField1); 

  textField2 = new JTextField("How many accounts to enter data for?",20);
  add(textField2); 

  textField3 = new JTextField("Enter account #",20);
  add(textField4); 

  textField3 = new JTextField("Enter data for account",20);
  add(textField5); 

1. If the user enters "4" into textField2, I would like "Enter account #" and "Enter data for account" to then appear four times (resulting in 8 new textfields)

2. I would like the user to be able to click a "Store" button that places textfields 1-5 (and more if they want to enter a lot of accounts) into an arraylist that can later be retrieved and print all stored array info (show all resident and all accounts info), similar to something like below:

    ArrayList accounts = new ArrayList<>();
   \n\n
   Account exampleAccount = new Account(); exampleAccount.setFirstName("John");  exampleAccount.setLastName("Doe");  exampleAccount.setBalance(101.13d); 
   \n\n
   accounts.add(exampleAccount);
   \n\n
   for(Account account : accounts) { System.out.println("Name: " + account.getFirstName() + " " + account.getLastName() + ". Balance: " + account.getBalance());  // Or override Account's toString() method and do System.out.println(account.toString()) } 

3. Would like the form "reset" so that after each time the user clicks "Store" they can enter a new resident's information.

How do I go about doing this?

Answer 1

You need something like this..

    textField1 = new JTextField("Enter resident name", 20);
    add(textField1);

    textField2 = new JTextField("How many accounts to enter data for?", 20);
    add(textField2);

    textField2.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {

            int count = Integer.valueOf(textField2.getText());

            for (int i = 1; i <= count; i++) {
                textField3 = new JTextField("Enter account #", 20);
                add(textField4);

                textField3 = new JTextField("Enter data for account", 20);
                add(textField5);
            }

        }
    });
