Java - createImageIcon() not recognized in code?

Question

I keep getting an error that createImageIcon() is not recognized as an available function. Not sure why this is occuring, as I feel like I have loaded the libraries that I need for it.

ImageIcon icon = createImageIcon("images/middle.gif","this is a caption");

I've tried using different arguments, etc., but can't seem to figure it out.

import javax.swing.*;
import javax.swing.ImageIcon;
import java.awt.*;
import java.awt.image.BufferStrategy;

public class main extends JFrame {

    public main() {

    }

    public static void main(String[] args) {
        JMenuBar menuBar = new JMenuBar();
        JMenu Menu_File = new JMenu("TEST MENU");
        JMenu Menu_File_New = new JMenu("New");
        ImageIcon icon = createImageIcon("images/middle.gif","this is a caption");
        Menu_File.add(Menu_File_New);
        JMenuItem Menu_File_New_Project = new JMenuItem("Project...");
        JMenuItem Menu_File_New_Burrito = new JMenuItem("Burrito...");
        JMenuItem Menu_File_New_Cookie = new JMenuItem("Cookie...");
        JMenuItem Menu_File_New_Other = new JMenuItem("Other...");
        Menu_File_New.add(Menu_File_New_Project);
        Menu_File_New.add(Menu_File_New_Burrito);
        Menu_File_New.add(Menu_File_New_Cookie);
        Menu_File_New.add(Menu_File_New_Other);
        JMenuItem Menu_File_Open = new JMenuItem("Open...");
        JMenuItem Menu_File_Save = new JMenuItem("Save");
        JMenuItem Menu_File_SaveAs = new JMenuItem("Save As...");
        JMenuItem Menu_File_Reload= new JMenuItem("Reload");
        Menu_File.add(Menu_File_Open);
        Menu_File.add(Menu_File_Save);
        Menu_File.add(Menu_File_SaveAs);
        Menu_File.add(Menu_File_Reload);
        Menu_File.addSeparator();
        JMenuItem Menu_File_Screenshot = new JMenuItem("Take Screenshot");
        Menu_File.add(Menu_File_Screenshot);
        Menu_File.addSeparator();
        JMenuItem Menu_File_Exit = new JMenuItem("Exit");
        Menu_File.add(Menu_File_Exit);
        menuBar.add(Menu_File);
        JMenu Menu_Edit = new JMenu("Edit");
        JMenu Menu_Windows = new JMenu("Windows");
        JMenu Menu_Mode = new JMenu("Mode");
        JMenu Menu_Help = new JMenu("Help");
        menuBar.add(Menu_Edit);
        menuBar.add(Menu_Windows);
        menuBar.add(Menu_Mode);
        menuBar.add(Menu_Help);

        main frame = new main();
        frame.setJMenuBar(menuBar); // Create menu and associate with frame
        frame.setTitle("3DAirspace");
        frame.setUndecorated(true);
        //frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}

Should it actually be:

ImageIcon icon = new ImageIcon("images/middle.gif","this is a caption");

so that you're calling the constructor for a new ImageIcon object?
