#09 Criteria API JPA | JAVA PERSISTENCE API JPA | Tutorial | Java | JakartaEE

✅ JPA Criteria API
The Criteria API is one of the most common ways of constructing queries for entities and their persistent state. It is just an alternative method for defining JPA queries.

Criteria API defines a platform-independent criteria queries, written in Java programming language. It was introduced in JPA 2.0. The main purpose behind this is to provide a type-safe way to express a query.
In this video, we're going to use:

- SELECT
- WHERE
- DISTINCT
- ORDER BY
- GROUP BY

We’re going to use the EntityManager to create a CriteriaBuilder object.
After that, using the CriteriaBuilder we're going to create the CriteriaQuery. The CriteriaQuery is used to create a query object.

During this video, we are going to use the H2 database for database operations.
