To present your applet in a visually pleasing way, it's often handy to know the size of the screen that's available for output. Fortunately, a built-in AWT function makes determining this pretty easy:
import java.awt.*;
public class ScreenInfo {
public static void main(String argv[]) {
Toolkit tlk = Toolkit.getDefaultToolkit();
System.out.println("The current screen
resolution is " + tlk.getScreenSize());
}
}
