Commonly used methods
Below program illustrate the use of Progress Indicator:
Program to create Progress indicator: This program creates a progress indicator indicated by the name pb. The progress indicator will be created inside a scene, which in turn will be hosted inside a stage. The function setTitle() is used to provide title to the stage. Then a tile pane is created, on which addChildren() method is called to attach the progress indicator and the button inside the scene. Finally the show() method is called to display the final results.
