Learn Java from Scratch - A Beginner's Guide - Step 02 - Exploring Primary and Qualifier Annotations for Spring Componen

The video tutorial discusses handling multiple implementations in Spring Framework using annotations. It starts with an error due to multiple gaming console implementations and explains how to resolve it using @Primary and @Qualifier annotations. The @Primary annotation is used to give preference to a specific implementation, while @Qualifier allows for more precise bean selection. The tutorial demonstrates these concepts with examples involving Mario and Super Contra games, showing how to implement them in a game runner using constructor injection.

What happens when there are multiple implementations of the gaming console interface in Spring Framework?

How can you help Spring Framework choose a specific implementation when multiple candidates are found?

What is the significance of the @Primary annotation in Spring Framework?

What would happen if you add a qualifier to the Super Contra game in the context of Spring Framework?

Explain the difference between @Primary and @Qualifier annotations in Spring Framework.
