Fire Default Button on jTextField Action Performed

In my program have a JButton and JTextField.
I want jButton fire while press Enter key in JTextField
I'm not talking about KeyEvent.

private void jTextFieldActionPerformed(java.awt.event.ActionEvent evt) {                                            
    this.getRootPane().setDefaultButton(jButton1);
}

This just make JButton focus enabled after enter in JTextField
So when I will enter in JTextField it must fire JButton ActionEvent.

And have this code on jButton1 ActionPerformed method.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        JOptionPane.showMessageDialog(rootPane, "Hi!");
    }

So how can I make JButton fired on JTextField ActionEvent?
I tried following answer but in IDE it throwing exception.

Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: javax.swing.JButton.addActionListener

Solution

One way to achieve that (if i got this straight), is to add an ActionListener to the JTextField which will call JButton#doClick() method. (I think it is pretty clear what the doClick() method does).

An example:

import java.awt.FlowLayout;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;

public class FireButtonOnEnter extends JFrame {
    private static final long serialVersionUID = -7346953935931623335L;

    public FireButtonOnEnter() {
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setSize(400, 400);
        setLocationRelativeTo(null);
        getContentPane().setLayout(new FlowLayout());
        JTextField textField = new JTextField(15);
        JButton button = new JButton("Print Hello");
        button.addActionListener(e -> System.out.println("Hello world."));
        textField.addActionListener(e -> button.doClick());
        getContentPane().add(textField);
        getContentPane().add(button);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> new FireButtonOnEnter().setVisible(true));
    }
}
