        setForeground(Color.white);
        setFont(new Font("Dialog", 0, 24));

        SimpleScreenManager screen = new SimpleScreenManager();
        try {
            screen.setFullScreen(displayMode, this);
            try {
                Thread.sleep(DEMO_TIME);
            }
            catch (InterruptedException ex) { }
        }
        finally {
            screen.restoreScreen();
        }
    }


    public void paint(Graphics g) {
        g.drawString("Hello World!", 20, 50);
    }
}
 


I have had this error before and have tried the control-shift-o and that fixed my previous errors but this one has me confused. the program is supposed to open a full screen window for five seconds with hello world displayed and then close it. the error is SimpleScreenManager cannot be resolved to a type.

Yup unless SimpleScreenManager is a class you wrote or a class from a library or something, it isn't in the Java SE 1.6 (Java 6) API. That means you can't use it cause it's not there  Wink

To correct it just put the SimpleScreenManager class at same folder of that class above or put it on same package and import it.

thanks, I wrote the code for the simple_screen_manager but didn't move it into a class for that project.
