Most Dialogs present an error message or warning to a user, but Dialogs can present images, directory trees, or just about anything compatible with the main Swing Application that manages them.For convenience, several Swing component classes can directly instantiate and display dialogs.

To create simple, standard dialogs, you use theJOptionPane class. The ProgressMonitor class can put up a dialog that shows the progress of an operation. Two other classes, JColorChooser and JFileChooser, also supply standard dialogs. To bring up a print dialog, you can use thePrinting API. To create a custom dialog, use theJDialog class directly.The code for simple dialogs ussage be minimal.
