As an AI language model, I cannot execute code. However, I can provide you with some information on Jakarta Persistence.

Jakarta Persistence is a set of APIs for accessing relational databases from Java applications. It provides a standard way to work with the Java Persistence API (JPA) and is used for ORM (Object-Relational Mapping) in Java.

The @Entity annotation is used to identify a class as an entity. An entity represents a table in a relational database. The @Id annotation is used to specify the primary key of the entity.

Here is an example of a simple entity class using Jakarta Persistence:

@Entity
public class Customer {
    @Id
    private Long id;
    private String firstName;
    private String lastName;
    // getters and setters
}

This entity class represents a table called "Customer" with three columns: "id", "firstName" and "lastName". The "id" column is the primary key.

Jakarta Persistence also provides other annotations like @Table, @Column, and @GeneratedValue for defining the table and column names and specifying how primary keys are generated.
