Execute Java Swing GUI application from command-line

Question

I have Java files structure like:

Gadget.java
GadgetShop.java
Mobile.java
MP3Player.java

GadgetShop.java file contains main method

package thegadgetshop;

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

public class GadgetShop extends JFrame implements ActionListener 
{
....

I used this command to run the file:

javac GadgetShop.java

And I got these errors:

I don't know why its not compiling and running from CMD while its running fine in Netbeans. I really need to run it from CMD.

I also used this command but got same error:

javac -Xlint GadgetShop.java

Edit 1

I have this files structure in Netbeans:

And files and classes structure in folder directory:

As others have pointed out, you need to navigate to the folder where your project is to run it.
