Learn Java from Scratch - A Beginner's Guide - Step 09 - Exploring Spring Framework with Java - Review

The video tutorial provides an in-depth exploration of the Spring Framework, starting with fundamental concepts such as coupling, dependency injection, and key annotations. It then delves into advanced topics like lazy initialization, bean scopes, and lifecycle methods. The tutorial also covers the history of Java EE and Jakarta EE, and compares Java and XML configurations. Finally, it discusses Spring Stereotype annotations and offers a comprehensive overview of the Spring Framework's modules and projects.

What is the primary benefit of using Java interfaces to achieve loose coupling in Spring?

• It allows for faster execution of code.

• It reduces the size of the codebase.

• It enables the use of multiple inheritance.

• It allows for easier swapping of implementations.

Which of the following is NOT a type of bean scope in Spring?

• Singleton

• Session

• Prototype

• Global

What is the purpose of the @PostConstruct annotation in Spring?

• To initialize a bean before it is destroyed.

• To execute a method after a bean's dependencies are set.

• To mark a method for lazy initialization.

• To define a bean's scope.

How does XML configuration differ from Java configuration in Spring?

• XML configuration is faster to process.

• Java configuration does not support annotations.

• XML configuration is more concise.

• Java configuration is more type-safe.

Which Spring Stereotype annotation is typically used to indicate a class that provides business logic?

• @Controller

• @Component

• @Service

• @Repository
