如何使用按钮将JTextField值添加到字符串数组

import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;

public class TextFieldArrayExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("TextField Array Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        JTextField textField = new JTextField(20);
        JButton addButton = new JButton("Add to Array");
        
        ArrayList<String> stringArray = new ArrayList<>();
        
        addButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String text = textField.getText();
                if (!text.isEmpty()) {
                    stringArray.add(text);
                    textField.setText("");
                    System.out.println("Value added to array: " + text);
                }
            }
        });
        
        frame.getContentPane().add(textField);
        frame.getContentPane().add(addButton);
        frame.getContentPane().setLayout(new FlowLayout());
        frame.pack();
        frame.setVisible(true);
    }
}
