Information Dialog in JavaFX

To display an information dialog in JavaFX, you can use the Alert class from the javafx.scene.control package. The Alert class provides several types of predefined dialogs, including an information dialog.

Here is an example of how to display an information dialog in JavaFX:

import javafx.scene.control.Alert;

public class InformationDialogExample {
    public static void main(String[] args) {
        // Create an Alert object
        Alert alert = new Alert(Alert.AlertType.INFORMATION);

        // Set the dialog's title and content text
        alert.setTitle("Information Dialog");
        alert.setHeaderText(null);
        alert.setContentText("This is an information dialog.");

        // Show the dialog
        alert.showAndWait();
    }
}

This will display an information dialog with the title "Information Dialog" and the content text "This is an information dialog.".

The Alert class also provides several other methods that you can use to customize the appearance and behavior of the dialog, such as setGraphic() to set the dialog's icon, setResizable() to control whether the dialog can be resized, and setOnCloseRequest() to set an event handler for the dialog's close request event.

For more information on the Alert class and the other types of predefined dialogs it provides, you can refer to the JavaFX documentation.
