Constructor Injection In Java Spring In Hindi || Spring Core Module In Hindi

We can inject the dependency by constructor. The constructor-arg sub element of bean is used for constructor injection. Here we are going to inject

primitive and String-based values
Dependent object (contained object)
Collection values etc.

IoC Container
The IoC container is responsible to instantiate, configure and assemble the objects. The IoC container gets informations from the XML file and works accordingly. The main tasks performed by IoC container are:

to instantiate the application class
to configure the object
to assemble the dependencies between the objects
There are two types of IoC containers. They are:

BeanFactory
ApplicationContext
Difference between BeanFactory and the ApplicationContext
The org.springframework.beans.factory.BeanFactory and the org.springframework.context.ApplicationContext interfaces acts as the IoC container. The ApplicationContext interface is built on top of the BeanFactory interface. It adds some extra functionality than BeanFactory such as simple integration with Spring's AOP, message resource handling (for I18N), event propagation, application layer specific context (e.g. WebApplicationContext) for web application. So it is better to use ApplicationContext than BeanFactory.
