Java MCQ: Which annotation is used to mark a class as an entity in JPA?

Answer:

Explanation:

The @Entity annotation is used to mark a class as an entity in JPA. An entity represents a table in the database, and each instance of the entity class corresponds to a row in the table. The @Entity annotation tells the JPA provider to manage this class as a persistent entity.

Here’s an example of an entity class:

@Entity
public class Employee {
    @Id
    private Long id;

    private String name;

    // Getters and setters
}

In this example, the Employee class is marked as an entity using the @Entity annotation, and it will be mapped to a table in the database.

Entities are central to JPA as they represent the data that is persisted and managed by the application.
