Storing multiple textfield inputs

I've been working on project trying to store inputs inside an array via user inputs on the GUI.
The issue right now is I am unable to find something similar to the Scanner method's "input.next".

Thanks for any help that comes by

Here's what the GUI class that gets executed from my Main look like

import javax.swing.*;
import java.awt.event.*;
import java.util.*;
public class GUI implements ActionListener {
//Private the variables to make them accessible to other methods
private static JLabel orderLabel;
private static JTextField orderText;
private static JButton confirmButton;
public  GUI(){
JFrame window = new JFrame();
JPanel panel = new JPanel();
window.setSize(350, 200);
window.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
window.add(panel);
window.setTitle("Place your order");
panel.setLayout(null);
//Creating label for the order text field:
orderLabel = new JLabel("Your order:"); //Creates the label memory
orderLabel.setBounds(10, 20, 80, 25); //Creates bounds for the label
panel.add(orderLabel); //Adds the label to the window
//Creating the text field
orderText = new JTextField(); //Creates text field memory
orderText.setBounds(100, 22, 165, 25); //Creates text field bounds
orderText.addActionListener(this);
panel.add(orderText); //Adds the text field to the window
//Creating the button to confirm order
confirmButton = new JButton("Confirm order");
confirmButton.setBounds(90, 100, 170, 30);
confirmButton.addActionListener(this);//Links the button to the action listener method inside this file
panel.add(confirmButton);
window.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
List<String> list = new ArrayList<String>();
String input = orderText.getText();
String temp = input.next();
}
}

If you want to use the Scanner#next() method against the contents of a JTextField then just use a Scanner object to do that, for example:

List<String> list = new ArrayList<>();
Scanner input = new Scanner(orderText.getText());
while (input.hasNext()) {
list.add(input.next());
}

Of course you would want everything supplied within the JTextField to be delimited with a whitespace, for example:

Bread Milk Sugar Coffee

which would play out as a list looking something like this:

Bread
Milk
Sugar
Coffee

This of course may not be good enough since a lot of required items would contain more than one word, for example:

French Fries Whole Wheat Bread 2% Milk

which would play out as a list looking something like this:

French
Fries
Whole
Wheat
Bread
2%
Milk

Not what is really wanted. In this particular case you can use the Scanner#useDelimiter() method to specify the delimiter you plan to use when typing the desired items into the JTextField. So, if you decided to use a semicolon (;) as a delimiter between typed in items and you entered into the JTextField:

French Fries; Whole Wheat Bread; 2% Milk

The list would look more like:

French Fries
Whole Wheat Bread
2% Milk

The code would be:

List<String> list = new ArrayList<>();
Scanner input = new Scanner(orderText.getText());
input.useDelimiter("\\s{0,};\\s{0,}");
while (input.hasNext()) {
list.add(input.next());
}

To put this into your (sort of) runnable application:

import java.awt.event.*;
import java.util.*;
import javax.swing.*;
public class GUI extends JFrame implements ActionListener {
private static final long serialVersionUID = 1L;
//Private the variables to make them accessible to other methods
private static JLabel orderLabel;
private static JTextField orderText;
private static JButton confirmButton;
public GUI() {
initializeForm();
}
private void initializeForm() {
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
setSize(350, 200);
setAlwaysOnTop(true);
setTitle("Place your order");
setLocationRelativeTo(null);
JPanel panel = new JPanel();
panel.setLayout(null);
//Creating label for the order text field:
orderLabel = new JLabel("Your order:"); //Creates the label memory
orderLabel.setBounds(10, 20, 80, 25); //Creates bounds for the label
panel.add(orderLabel); //Adds the label to the window
//Creating the text field
orderText = new JTextField(); //Creates text field memory
orderText.setActionCommand("orderText");
orderText.setBounds(100, 22, 165, 25); //Creates text field bounds
orderText.addActionListener(this);
panel.add(orderText); //Adds the text field to the window
//Creating the button to confirm order
confirmButton = new JButton("Confirm order");
confirmButton.setActionCommand("confirmButton");
confirmButton.setBounds(90, 100, 170, 30);
confirmButton.addActionListener(this);//Links the button to the action listener method inside this file
panel.add(confirmButton);
add(panel);
}
public static void main(String[] args) {
new GUI().setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
String textToTokenize = orderText.getText().trim();
// TRY to determine the delimiter used within the JTextField entry
String delimiter = textToTokenize.replaceAll("[^:;'\"\\|\\\\~!@#$%\\^&\\"
+ "*-_+=<>.?/]", "").trim();        
if (delimiter.length() == 0) {
delimiter = " ";
}
else {
delimiter = delimiter.substring(0, 1);
}
if (!textToTokenize.isEmpty() && 
(e.getActionCommand().equals("confirmButton") || 
e.getActionCommand().equals("orderText"))) {
List<String> shoppingList = new ArrayList<>();
// If you want to use Scanner's next() method then 
// just use Scanner to do it...
Scanner input = new Scanner(textToTokenize);
input.useDelimiter("\\s{0,}" + delimiter + "\\s{0,}");
while (input.hasNext()) {
shoppingList.add(input.next());
}
// Test...Display list in console window:
JOptionPane.showMessageDialog(this, "<html>Supplied shopping list items are:"
+ "<br><br><center><font color=blue>" + shoppingList.toString()
.replaceAll("[\\[\\]]", "") + "</font></center><br></html>", 
"Supplied List...", JOptionPane.INFORMATION_MESSAGE);
}
orderText.setText("");
orderText.requestFocus();
}
}
