Master Hibernate and JPA with Spring Boot in 100 Steps - Step 10 - Quick Review and Debugging Tips

The video tutorial covers creating a demo application using Spring Initializer, focusing on building a course entity and repository for CRUD operations. It explains the importance of primary keys and JPA requirements. The tutorial also delves into unit testing with a focus on maintaining data integrity using Dirties Context. Additionally, it introduces the use of a command line runner and debugging techniques to enhance understanding of the application's behavior.

What is the primary purpose of the course repository in the demo application?

• To handle network requests

• To perform CRUD operations on the course entity

• To generate reports

• To manage user authentication

What is the role of a primary key in a database table?

• An entity is a bean that maps to a database row

• An entity is not stored in the database

• An entity cannot have methods

What does the DirtiesContext annotation ensure in unit tests?

• That the user interface is updated

• That the code is compiled

How can you set a breakpoint in a Java application for debugging?

• By pressing Ctrl+C

• By double-clicking in the margin of the code editor

• By opening the task manager

• By right-clicking the console

What is the purpose of using debug mode in a Java application?

• To increase application speed

• To check the application's behavior step by step

• To deploy the application

• To generate random data
