The interface org.hibernate.Criteria represents a query
against a particular persistent class. The Session is a
factory for Criteria instances.

Criteria crit = sess.createCriteria(Cat.class);
crit.setMaxResults(50);
List cats = crit.list();

Answer / sushant

Hibernate is a replacement of DAO layer used in traditional
JDBC based applications.

And similarly you can say that Criteria is a replacement for
query to the DB.

Used somewhat like...

Session session = sessionFactory.openSession();
Criteria demoCriteria = session.createCriteria(Animal.class);

....
later you can set some property or restrictions in the query...

demoCriteria.add( Restrictions.like("name", "Dog%") )..
...etc.
..
and then execute this criteria to get the results.

List resultsList = demoCriteria.list();

hope that helps.
Mail me for some more info if you require some.
