Question

As i can see only list method in query class in hibernate.How to get set or array directly from query in hibernate?

 Query q = session.createQuery("from com.daasl.Person");
 List<Person> l = q.list();

Is there a way i can get set or array directly instead of list?

Answer 1

Query can only return a list .

But you can convert the generic list to the generic array using the toArray(T[] a) of the java standard Collection interface

 Query q = session.createQuery("from com.daasl.Person");
 List<Person> personList = q.list();
 Person[] personArray = personList .toArray((Person[])Array.newInstance(Person.class, personList .size()));

To convert the list to a set , just supply the list to the constructor of the HashSet

  Set<Person> personSet = new HashSet<Person>(personList);
