Chapter 19. Introduction to the Java Persistence API > Querying Entities
Querying Entities
The Java Persistence API provides the following methods for querying entities.
The Java Persistence query language (JPQL) is a simple, string-based language similar to SQL used to query entities and their relationships. See Chapter 21, “The Java Persistence Query Language,” for more information.
The Criteria API is used to create typesafe queries using Java programming language APIs to query for entities and their relationships. See Chapter 22, “Using the Criteria API to Create Queries,” for more information.
