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 | Boxes like this one hold important, not-to-be forgotten information that is directly relevant to the surrounding text. |
Note | Tips, hints, tricks, and asides to the current discussion are offset and placed in italics like this. |
As for styles in the text:
New terms and important words are highlighted when they're introduced.
Keyboard combination strokes appear like this: Ctrl+A.
Filenames, URLs, and code within the text appear in a monospaced font, like this: persistence.properties.
Code is presented in two ways:
A gray background highlights examples of new and important code. The gray highlighting is not used for code that's less important in the present context, or that has been shown before.
