JDialog

JDialog is Swing's version of Dialog and is descended directly from that class. Like Dialog, it uses BorderLayout by default. Like JFrame and JWindow, JDialog contains a rootPane hierarchy including a contentPane, and it allows layered and glass panes. All dialogs are modal, which means the current thread is blocked until user interaction with it has been completed. JDialog class is intended as the basis for creating custom dialogs; however, some of the most common dialogs are provided through static methods in the class JOptionPane.
• JLabel, descended from JComponent, is used to create text labels.
• The abstract class AbstractButton extends class JComponent and provides a foundation for a family of button classes, including
JButton.
• JTextField allows editing of a single line of text. New features include the ability to justify the text left, right, or center, and to set the text's font.
