What is ADF Task Flow, and How Is It Different from JSF Navigation?

ADF Task Flow is a powerful feature in Oracle ADF that allows developers to define and manage the flow of an application. It provides a visual representation of the application's navigation and can be used to create complex and dynamic user interfaces.

ADF Task Flow is different from JSF Navigation in several key ways:

• Declarative vs. programmatic: ADF Task Flow is declarative, meaning that it is defined using a visual editor rather than writing code. JSF Navigation, on the other hand, is programmatic and requires developers to write code to define the navigation rules.
• State management: ADF Task Flow manages the state of the application, including the current page, active bindings, and available actions. JSF Navigation does not provide built-in state management, and developers must manually manage the state of the application.
• Extensibility: ADF Task Flow is extensible, allowing developers to create custom task flows and components. JSF Navigation is not as extensible and does not provide the same level of customization.

ADF Task Flow provides several benefits over JSF Navigation, including improved productivity, reduced development time, and better maintainability. Oracle ADF Interview Questions on ADF Task Flow assess candidates' understanding of this important feature and their ability to use it effectively in their applications.
