Q1: What is JPA?
A1: JPA stands for Java Persistence API. It is a
Java specification for object-relational mapping
(ORM) that provides a programming interface
to manage relational data in Java applications
using object-oriented concepts.

Q2: What is the difference between JPA and
Hibernate?
A2: JPA is a specification that defines the standard API
for ORM in Java, while Hibernate is an implementation
of that specification. Hibernate provides additional
features beyond what is defined in the JPA
specification. However, using JPA allows for more
portability and the ability to switch between different
JPA implementations without changing the code.

Q3: How can you perform pagination with JPA?
A3: Pagination can be achieved in JPA by using the
setFirstResult() and setMaxResults() methods of
the Query or TypedQuery interface. The
setFirstResult() method sets the index of the first
result to retrieve, and the setMaxResults() method
specifies the maximum number of results to
retrieve.
