How to do this

[impact]

Hi,
I am learning java. so I keep doing things in a different way to learn what I am trying to do
For example here I am trying to call

package components;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

/* FrameDemo.java requires no other files. */
public class ABC extends JFrame{
    /**
     * Create the GUI and show it.  For thread safety,
     * this method should be invoked from the
     * event-dispatching thread.
     */
	
	public JLabel label;
	
	
	
	
	/**
	 * This class should add instruction to the existing frame
	 * By using a Jlable = label
	 * A text field
	 */
	
	class Text {
		public JTextField info, number;
		
		public Text(){    
			// Text information to the user
			info = new JTextField("Enter the number"); 
			info.setEditable(false);
			
			// Empty text field for number entry
			number = new JTextField(15);
			}
	}
	
	public ABC() {
		
		Container c = getContentPane();
		c.setLayout(new FlowLayout());
		
// tried this but dont work
		Text info = new Text();
		info.add();
	}
    private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame frame = new JFrame("FrameDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JLabel emptyLabel = new JLabel("");
        emptyLabel.setPreferredSize(new Dimension(600, 400));
        frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
        
//      Create and set up the content pane.
         
//This dont work too
        frame.add( new Text());

        //Display the window.
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

Can you please show me how should I call the Text() in Text class in the ABC () to make it visible in the frame?

Thank you
