Instructions and help about XML Programming In Java Technology, Part 3

in this video we will see how to apply dependency injection principles to our code examples using Spring Framework with XML configuration in the previous video you saw how to perform manual dependency injection by manually creating the objects we want and passing them into the email client class now we will see how to use Spring Framework to pass dependency into our classes so Spring Framework provides us a way to automatically create objects and inject them into our application at runtime this functionality is provided by something called as a spring IOC container the spring IOC container is responsible to create our objects and maintain its entire lifecycle so instead of manually creating the objects in our code using the new keyword we can ask spring for objects we want and it injects them at runtime one of the ways to do this is by specifying all the objects we need inside an XML file then the spring IOC container reads this XML file and will create the required objects and inject
