Question - What Is the Difference Between BeanFactory and ApplicationContext?
Answer -
BeanFactory is an interface representing a container that provides and manages bean instances. The default implementation instantiates beans lazily when getBean() is called.
In contrast, ApplicationContext is an interface representing a container holding all information, metadata and beans in the application. It also extends the BeanFactory interface, but the default implementation instantiates beans eagerly when the application starts. However, this behavior can be overridden for individual beans.
For all differences, please refer to the documentation.
