JProgressBar is a Java Swing component that visually displays the progress of some task.

JProgressBar is a Java Swing component that visually displays the progress of some task. As the task progresses towards completion, the progress bar displays the task's percentage of completion. This percentage is typically represented visually by a rectangle which starts out empty and gradually becomes filled in as the task progresses. In addition, the progress bar can display a textual representation of this percentage.

For details and examples see How to Use Progress Bars tutorial.
