Hi friend,

A JWindow is a container that can be displayed anywhere on the user's desktop. It does not have the title bar, window-management buttons, or other trimmings associated with a JFrame, but it is still a "first-class citizen" of the user's desktop, and can exist anywhere on it. The JWindow component contains a JRootPane as its only child. The contentPane should be the parent of any children of the JWindow.

JWindow class is used as a one of he container in java. It is very simple to use this JWindow class. Following program shows the use of the JWindow() method of this class:

import javax.swing.JWindow;

public class JWindowDemo

{
  public static void main(String arg[]) 

  {
    JWindow w1 = new JWindow(  );

    w1.setSize(200, 000);
    w1.setLocation(400, 100);

    w1.setVisible(true);

  }

}

A JWindow class comprises number of constructors. 'JWindow(Window ownerName) is one it's important constructor. This constructor of JWindow is used only when you want to create window along with the particular owner window. While the 'JWindow(GraphicsConfiguration gpc)' constructor of JWindow is used when you create a window which has particular GraphicsConfiguration for the screen device.
