Eclipse : how exit full screen

Newbie & Debugging Questions
#1

I was running this code ( 3D from scratch youtube tutorial) ):


import java.awt.Toolkit;

import javax.swing.JFrame;

public class DDDTutorial extends JFrame
{
	static JFrame F = new DDDTutorial();

	public DDDTutorial()
	{
		setUndecorated(true);
		setSize(Toolkit.getDefaultToolkit().getScreenSize());
		setVisible(true);

	}

	public static void main(String[] args)
	{

	}

}

and i don’t know how to exit the full screen.
ctrl + esc lets me close the window ( i’m on windows7) but eclipse says that
the application is still running.
Googling here and there i didn’t find a “solution”.
Thx !!!
