Thanks for addding good points and explanation. I have one doubt. If we use @Qualifer and give be bean ID. Doesn't it violate runtime polymorphism of our interface?

Super topic. One suggestion is please change the title to Spring Core so that youtube can catch it easily. I assume this is the #primary topic #qualified in commonly #required Spring core terminologies.

I want to add one thing here.
Create Empty constructor. with Autowired Constructor with Animal Param ( having qualifier ("dog")
then it will work.
