Conventions

Throughout the book, concrete programming constructs or program output are

presented in a monospaced font. For example, when abstractly discussing

server side programs that use HTTP, I might refer to  HTTP servlets  or just

 servlets,  but when I say 

HttpServlet

 I am talking about a specific Java class.

User input is indicated in boldface, and command line prompts are either

generic (

Prompt>

) or indicate the operating system to which they apply

(

DOS>

). For instance, the following indicates that  

Some Output

  is the result

when  

java SomeProgram

  is executed on any platform.

Prompt> java SomeProgram

Some Output

Important standard techniques are indicated by specially marked entries,

as in the following example.

Core Approach

Pay particular attention to items in  Core Approach  sections. They indicate 

techniques that should always or almost always be used.

Notes and warnings are called out in a similar manner.
