Question - Difference between the transient, persistent and detached state in Hibernate?

Answer -

Transient state: New objects are created in the Java program but are not associated with any Hibernate Session.
Persistent state: An object which is associated with a Hibernate session is called Persistent object. While an object which was earlier associated with Hibernate session but currently it’s not associate is known as a detached object. You can call save() or persist() method to store those object into the database and bring them into the Persistent state.
Detached state: You can re-attach a detached object to Hibernate sessions by calling either update() or saveOrUpdate() method.
