Java Developer Interview at Infosys Pune : Full Real Question Set

Hey guys, welcome back to my channel Java interview buddy. Today's questions are from Prakash Reddi. He's one of our subscriber. He recently faced an interview at Infosys and he has around 3.4 years of experience in Java, Spring Boot and microservices and honestly Infosys is hiring so aggressively right now. I'm getting an overwhelming amount

of interview questions from you all. All right, so let's start the video. How does dependency injection work in Spring Boot internally? So dependency injection simply means spring creates objects for you. It scans all the classes, find component and creates beans. These beans are stored in a application context. Whenever your class needs something,

Spring inject it automatically. Internally, Spring uses reflection and proxies to manage this. And this is one of the favorite question of interviewer in every interview about the Spring Boot. 99% of the time they ask this question. You should prepare this question very well. Now coming to our next question which is what happens when

you start a spring boot application internally. So this is also a very important question and you can explain it like this. When you run the main class spring application run method starts everything. It triggers auto configuration. It scans the packages. It creates the beans and setup dependencies as well. It triggers the auto

configuration. It scans the packages. Then it loads your config and finally it start the embedded TomKit server. The next question is very so before we jump to our next question, I have a quick update for you. Our interview kit is live now and you can find it in the description of this video or any other
