Managed Beans vs Backing Beans in JavaServer Faces (JSF)

In JavaServer Faces (JSF), managed beans and backing beans are both used to manage application data and logic, but they serve different purposes.

Managed Beans

Managed beans are ordinary Java classes that are managed by the JSF framework. These beans are typically used to store and manage application data, perform business logic, and interact with the UI components.

Backing Beans

Backing beans are a type of managed bean that specifically handles navigation and data transfer between the UI components and the business logic. They are often associated with a specific view in the application and are used to bind the UI components to the backend data.

It's important to note that while all backing beans are managed beans, not all managed beans are backing beans. Managed beans have broader use cases, while backing beans are more focused on the UI-related tasks.

Understanding the difference between managed beans and backing beans is crucial for developing efficient and maintainable JSF applications.
