GUI Error

[Kid Programmer]

Hello guys. I am receiving an error while creating a program that will capitalize words entered in a text box. I have 2 files with code. Here they are:
File No. 1:

package capitalizeme;

import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JButton;
import java.awt.Container;
import java.awt.FlowLayout;

public class CapitalizeMe {

    public static void main(String[] args) {
        JFrame frame;
        Container contentPane;
        JTextField textfield;
        JButton button;
        FlowLayout layout;
        
        frame = new JFrame();
        frame.setTitle("Handy capitalization service");
        
        contentPane = frame.getContentPane();
        
        textfield = new JTextField("Type your text here.", 20);
        
        button = new JButton("Capitalize");
        button.addActionListener(new MyActionListener(textfield));
        
        contentPane.add(textfield);
        contentPane.add(button);
        layout = new FlowLayout();
        
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}

File No. 2:

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

class MyActionListener implements ActionListener {

	JTextField textfield;
	
	MyActionListener(JTextField textfield) {
		this.textfield = textfield;
	}

	public void actionPerformed(ActionEvent e) {
		textfield.setText(textfield.getText().toUpperCase());
	}
}

Here is my error:
symbol : class MyActionListene r
location: class capitalizeme.Ma in
button.addActio nListener(new MyActionListene r(textfield));

What's the actual error it's giving you? You've told us what line, but not what it's telling you is wrong with that line.

The error is:

cannot find symbol

I think this is a package/scope error. Add a package statement to the second file and that should help.
