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: These Are Exercises or Examples for You to Follow

The Try It Out sections, which appear once or more per chapter, provide hands-on exercises that demonstrate the concept under discussion as you follow the text.

1. They consist of numbered steps.
2. Follow the steps with your copy of the project files.

How It Works

After each Try It Out section, these sections explain the code you've typed in detail.

As for other conventions in the text:

• New terms and important words are highlighted in italics when first introduced.
• Keyboard combinations are treated like this: Control-R.
• Filenames, URLs, and code within the text are treated like so: persistence.properties.
• Code is presented in two different ways:

  We use a monofont type with no highlighting for most code examples.
  
  We use bold to emphasize code that is of particular importance in the present context.

WARNING Boxes like this one hold important, not-to-be forgotten information that is directly relevant to the surrounding text.

NOTE Notes, tips, hints, tricks, and asides to the current discussion look like this.
