Master Hibernate and JPA with Spring Boot in 100 Steps - Step 40 - ManyToMany Mapping - Insert Student and Course

The video tutorial explains how to manage many-to-many relationships in JPA by creating and persisting student and course entities. It covers the process of establishing relationships between these entities, debugging the execution, and transitioning from hardcoded to dynamic values. The tutorial concludes with a demonstration of the final execution and encourages viewers to explore additional methods for adding courses to students and vice versa.

What is the primary focus of the initial setup in the JPA tutorial?

• Designing a user interface

• Creating a new database

• Establishing a many-to-many relationship

• Configuring a web server

Which method is used to persist entities in JPA?

• entityManager.store()

• entityManager.insert()

• entityManager.save()

• entityManager.persist()

How is the relationship between a student and a course established in the code?

• By using a foreign key

• By using a trigger

• By adding the course to the student and vice versa

• By creating a new table

What happens when the student entity is persisted?

• An ID is assigned to the student

• The student is deleted

• The student is ignored

• The student is updated

What does Hibernate do before executing updates on the database?

• It cancels the updates

• It logs the updates without executing

• It waits until the transaction is closed

• It immediately executes each update

What is the purpose of removing hardcoded values in the code?

• To reduce the file size

• To improve security

• To allow dynamic insertion of data

• To make the code more readable

What exercise is suggested for further practice?

• Designing a new user interface

• Adding a course to a student or vice versa

• Implementing a caching mechanism

• Creating a new database schema
