Class SwingWorker

Class SwingWorker (in package javax.swing) enables you to perform an asynchronous task in a worker thread (such as a long-running computation) then update Swing components from the event dispatch thread based on the task’s results. SwingWorker implements the Runnable interface, meaning that a SwingWorker object can be scheduled to execute in a separate thread. The SwingWorker class provides several methods to simplify performing a task in a worker thread and making its results available for display in a GUI. Some common SwingWorker methods are described in Fig. 23.23.
