Question: How do I determine the width and height of my application?

Answer: Use the getSize() method, which the Applet class inherits from the Component class in the Java.awt package. The getSize() method returns the size of
the applet as a Dimension object, from which you extract separate width, height fields. The following code snippet explains this:

Dimension dim = getSize();
int appletwidth = dim.width();
int appletheight = dim.height();
