Conventions

To help you get the most from the text and keep track of what's happening, we've used a number of conventions throughout the book.

Important 

These boxes hold important, not-to-be-forgotten information, which is directly relevant to the surrounding text.

Note 

While the background style is used for asides to the current discussion.

As for styles in the text:

• When we introduce them, we highlight important words

• We show keyboard strokes like this: Ctrl-K

• We show filenames and code within the text like so: persistence.properties

• Text on user interfaces and URLs are shown as: Menu

We present code in two different ways:

     In our code examples, the code foreground style shows new, important, pertinent     code.                                                                                                                       While code background shows code that's less important in the present context, or     has been seen before.
