SwingWorker

SwingWorker is a class in the Java Swing library that allows long-running tasks to be executed asynchronously on a separate thread from the main thread of a Swing application. It was introduced in Java 1.6 as a replacement for the earlier SwingUtilities class, which did not provide a mechanism for handling long-running tasks.

SwingWorker provides a convenient way to perform time-consuming tasks in the background, while still allowing the user interface to remain responsive. It also provides a mechanism for reporting progress and results back to the user interface thread, allowing the user to monitor the progress of the task and interact with the application while the task is running.

SwingWorker is typically used to perform tasks such as network communication, file I/O, database queries, or any other operation that may take a significant amount of time to complete. By executing these tasks on a separate thread, the user interface remains responsive and the application remains interactive, even while the task is running.

Overall, SwingWorker is a powerful tool for building highly responsive Swing applications that can handle long-running tasks without sacrificing the user experience.
