How do I use JPA in my Java application?

To use JPA, you need to set up your project with the necessary dependencies, like Hibernate or EclipseLink.

What dependencies do I need to include?

You typically need to include the JPA API and a JPA provider like Hibernate in your Maven or Gradle configuration.

Can you give me an example of a simple entity class?

Sure! Here's a simple example:

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    private String email;

    // Getters and Setters
}

How do I perform CRUD operations using JPA?

You can use the EntityManager to persist, find, merge, and remove entities. Would you like a code example?
