What are some examples of using the criteria API?

The criteria API is used for building dynamic queries in a type-safe manner. For example, you can use it to filter data based on specific conditions.

Can you give me a specific code example?

Sure! Here's a simple example in Java:

CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<YourEntity> cq = cb.createQuery(YourEntity.class);
Root<YourEntity> root = cq.from(YourEntity.class);

cq.select(root).where(cb.equal(root.get("fieldName"), "value"));
List<YourEntity> results = entityManager.createQuery(cq).getResultList();

What are the advantages of using the criteria API over JPQL?

The criteria API provides type safety, allows for dynamic query generation, and is easier to refactor since it uses Java code instead of string-based queries.
