JOptionPane

Used in Swing for simple pop-up modal dialog boxes to interact with the user, sort of a streamlined JDialog to handle common cases.

Dialog is the AWT equivalent of JoptionPane. Here are some typical examples:

// sample use of JOptionPane.showMessageDialog
import javax.swing.JOptionPane;

JOptionPane.showMessageDialog( this,
                               "That name is already taken.",
                               "Duplicate Name",
                               JOptionPane.ERROR_MESSAGE );

Finally, there is showOptionDialog: the Grand Unification of the above three, which I have not shown.
