How do I limit the result data by using limit in criteria

Question

How do I add 'limit value' in Hibernate criteria.

My code is like this

Criteria criteria = session.createCriteria(Sample.class);
criteria.add(Restrictions.eq("colOne", colOne));
criteria.add(Restrictions.eq("colThree", colThree));
criteria.addOrder(Order.desc("colFour"));

How do i retrieve a single row instead of a list?

Answer 1

Get first element form your list and do cast with your class.

Sample sample= (Sample)ctriteria.list().get(0);  

Answer 2

You can use setMaxResults:

public Criteria setMaxResults(int maxResults)
