Answer 1

Spring supports multiple bean scopes, including Singleton, Prototype, Request, and Session. These bean scopes define the lifecycle and visibility of a bean in a Spring application.

Step-by-step explanation:

Spring supports multiple bean scopes, including Singleton, Prototype, Request, and Session. These bean scopes define the lifecycle and visibility of a bean in a Spring application.

The Singleton scope creates a single instance of a bean that is shared across the entire application. The Prototype scope creates a new instance of a bean each time it is requested. The Request scope creates a new instance of a bean for each HTTP request, and the Session scope creates a new instance of a bean for each user session.

Each scope has its own use case, and it's important to understand the differences and choose the appropriate scope for each bean in your application.
