Master Java Web Services and REST API with Spring Boot- Step 12 - Implementing a service - Course Details Service - back

The video tutorial guides viewers through creating a Java bean with fields and methods, implementing a service layer for course management, and connecting the service to an endpoint. It covers creating a static list of courses, implementing methods to find and delete courses, and using iterators to avoid concurrent modification exceptions. The tutorial concludes with refactoring the code using mappers to improve logic separation.

What is the primary purpose of creating a Java bean in this context?

• To process payment transactions

• To manage network connections

• To handle user authentication

• To store and manage course details

Which annotation is used to inject the CourseDetailService into the Java bean?

• @Autowired

• @Service

• @Component

• @Inject

What is the role of the findById method in the CourseDetailService?

• To add a new course

• To retrieve a course by its ID

• To update course details

• To list all available courses

Why is an iterator used in the deleteById method?

• To improve performance

• To avoid concurrent modification exceptions

• To simplify the code

• To enhance security

What is the purpose of the map method introduced during refactoring?

• To convert course details into a response format

• To encrypt course data

• To log course access

• To validate course inputs

What is the benefit of using mappers in the refactored code?

• To reduce memory usage

• To improve code readability and organization

• To increase execution speed

• To enhance security features

What is the final step mentioned in the video regarding the course management application?

• Deploying the application

• Testing the application

• Refactoring the code

• Documenting the code
