}// End JTabbed frame constructor

}//end class

for this code to compile here is my second .java file

public class JTabbedPaneDemo

{

public static void main(String[]args)

{

AFrame aFrame = new AFrame();

aFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

aFrame.setSize(680,420); // frame size

aFrame.setVisible(true);

}

}
