Font and Naming Conventions

We use fonts to distinguish between on-screen components (such as menu names and menu items) and Java code or commands. Our convention is to emphasize on-screen components in a sans-serif bold Helvetica font (for example, File menu) and to emphasize Java code and commands in a sans-serif Lucida font (for example, System.out.println()).
