"Examplets" are code snippets that illustrate a particular task.
They're designed to show which classes and members are
involved in performing the task, and how the classes and
members interact with each other. You will see blue italicized
text in an examplet; this indicates code that should be replaced
if you use it in your program.
An examplet can have enough detail for you to use it, as is. Or
you might have to get more information about the involved
classes. A good place to find information about the Java 2
Platform APIs is the Java 2 Platform API index.
It's also good practice to add catch clauses, as appropriate, to
the examplets. If the code of an examplet throws a checked
exception, the code is surrounded by a try/catch statement.
However, to reduce space and distraction, the catch clause is
left blank. Catch clauses should always handle the exception
and should never be left blank. So, at the very least, you
should include a call to e.printStackTrace() to display the exception
on the console.
You'll find examplets in a variety of categories. See the Table of
Contents for a list of categories, and the examplets in each category.
