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.
| Note | Tips, hints, tricks, and asides to the current discussion are offset and placed in italics like this. |
As for styles in the text:
We italicize important words when we introduce them.
We show keyboard strokes like this: Ctrl+A.
We show filenames, URLs, and code within the text like so: persistence.properties
We present code in two different ways:
In code examples we highlight new and important code with a gray background.
The gray highlighting is not used for code that's less important in the present
context, or has been shown before.
