Master Hibernate and JPA with Spring Boot in 100 Steps - Step 43 - JPA Inheritance Hierarchies and Mappings - Setting Up

The video tutorial covers the creation of an inheritance hierarchy for employee entities. It begins with defining an abstract Employee class, followed by the implementation of Part-Time and Full-Time Employee classes. The Part-Time Employee class includes an hourly wage attribute, while the Full-Time Employee class includes a salary attribute. The tutorial also discusses constructors and methods for these classes, setting the stage for creating a repository to manage employee data.

What is the purpose of making the 'Employee' class abstract?

• To allow direct instantiation of Employee objects

• To prevent the creation of Employee instances directly

• To add more attributes to the Employee class

• To simplify the code structure

Which attribute is unique to the 'PartTimeEmployee' class?

• Salary

• Hourly wage

• ID

• Name

What is the main difference between 'PartTimeEmployee' and 'FullTimeEmployee' classes?

• FullTimeEmployee has no unique attributes

• PartTimeEmployee has a salary attribute

• FullTimeEmployee has an hourly wage attribute

What is the primary attribute added to the 'FullTimeEmployee' class?

• Hourly wage

• ID

• Salary

• Name

What is the next step after defining the employee entities?

• Adding more attributes to the classes

• Developing a repository to manage employee data

• Creating a user interface

• Testing the classes with sample data
