What is the Hibernate ORM Criteria API?

The Hibernate ORM Criteria API is a powerful way to create queries for retrieving data from a database using an object-oriented approach.

How does it differ from HQL?

Unlike HQL, which is a string-based query language, the Criteria API allows you to build queries programmatically using Java objects.

Can you give me an example of using the Criteria API?

Sure! For example, you can create a Criteria query to find all users with a specific role like this: CriteriaBuilder cb = session.getCriteriaBuilder(); CriteriaQuery<User> cq = cb.createQuery(User.class); Root<User> root = cq.from(User.class); cq.select(root).where(cb.equal(root.get("role"), "admin"));

Is it suitable for complex queries?

Yes, the Criteria API is well-suited for complex queries, allowing for dynamic query construction and better readability.
