Spring Framework Master Class - Java Spring the Modern Way - Step 14 - Scope of a Bean - Prototype and Singleton

The video tutorial explains the concept of bean scopes in Spring, focusing on Singleton and Prototype scopes. It describes how the application context manages beans and how different scopes affect bean instances. Singleton beans return the same instance, while Prototype beans create new instances. The video also briefly introduces request and session scopes for web applications and demonstrates how to configure bean scopes using annotations.
