EXTENDED-TASK THREADING WITH A SHELF LIFE

Threading isn't just for building better multitasking applications under
Java; it's also for handling long-running tasks that may encompass the
entire active session of a single program. Extended tasks are actions that
linger in the background, awaiting certain cues or user inputs to complete.

Like multitask threading, however, extended-task threading has its fair
share of common pitfalls. To avoid these threading problems, you must
properly build extended-task code from the ground up.

The Runnable interface and the abstract class Worker are the foundation
blocks for better extended-task Java apps. Building a stockpile of
modular code around these elements will ensure that your applications 
are stable and viable; it also saves you the hassle of making common 
mistakes every time you rebuild the code from scratch.

See a demonstration that explains how to employ threading as the
backbone of long-running application tasks, and shows you how to build 
out this functionality in a reusable form.
