JDialog

JDialog is a class in Java's Swing graphical user interface toolkit. It represents a dialog window, which is a special type of window that typically appears on top of the application's main window. Dialogs are often used for short, focused interactions with the user, such as displaying messages, getting simple input, or confirming actions.

A JDialog is a subclass of java.awt.Dialog and inherits its basic dialog window behavior. It can be modal or non-modal. A modal dialog blocks user interaction with the rest of the application until the dialog is closed. This is common for critical prompts or when specific user input is required. A non-modal dialog allows the user to continue interacting with the main application while the dialog remains open.

Key features of JDialog include its ability to contain other Swing components, such as buttons, text fields, and labels, to facilitate user interaction. It can be customized with a title, size, and position. Developers can define the behavior of a JDialog by adding action listeners to its components, allowing them to respond to user events like button clicks. JDialogs are often used in conjunction with JFrames, the main window of a Swing application. They provide a structured way to handle temporary user interactions without cluttering the main interface.
