What is the role and purpose of Bean components within the Spring Framework?

In the Spring Framework, Bean components are objects managed by the Spring container. They are the fundamental building blocks of an application and are created, configured, and managed by the container according to the configuration.

Role and purpose of a Bean:

• Encapsulation of business logic or services.
• Management of object lifecycle (creation, initialization, destruction).
• Providing dependency injection, which simplifies component coupling and facilitates testing.

For example, a service class annotated with @Service is automatically registered as a Bean and can be injected into a controller or another service via @Autowired.
