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.

---

TRY IT OUT   You should work through all the Try It Out exercises in the book.

1. These exercises consist of a set of numbered steps.
2. Follow the steps with your copy of the database.

HOW IT WORKS

At the end of each Try It Out, the code you've typed will be explained in detail.

As for styles in the text:

• We italicize new terms and 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:

We use a monofont type with no highlighting for most code examples.
We use bold to emphasize code that is particularly important in the present
  context or to show changes from a previous code snippet.
