Dialogs are popup windows for communicating with the user for a specific purpose such as:

• Warnings
• Messages
• Queries
• Selection of a directory and/or files, typically for saving or opening a file.

A dialog window acts in two ways:

• Modal - becomes the top window and will not release control to any other window until it is answered and closed.
• Nonmodal - can become a secondary window while waiting to be answered and closed.

• Create a subclass of JFrame and add dialog functionality yourself such as a window closing mechanism.
  
  
• Subclass JDialog, which is a subclass of JFrame and provides various capabilities such as modal/non-modal behavior.
  
  
• Use JOptionPane and its various methods such as showConfirmDialog() and showMessageDialog() to generate basic dialogs with icons, buttons, message text, and closing mechanism.
  
  
• Use JFileChooser and JColorChooser for selecting files/directories and colors, resp.

Generally, the JOptionPane approach is the much easier one for basic dialogs and the two chooser classes are excellent for their tasks. Create a JDialog subclass when you need a more elaborate dialog with, for example, checkboxes or other components that provide the user with multiple options. JFrame subclasses should generally be reserved for more complex tasks that require a fully developed window.

In the following pages we provide demo programs to illustrate dialogs with JOptionPane
