When a session.save( ) is passed to a transient mapped object it makes the method to become more persistent. Garbage collection and termination of the Java virtual machine stays as long as it is deleted explicitly. It may head back to its transient state.

In the context of Hibernate, which is a popular Java framework for Object-Relational Mapping (ORM), the transient keyword is used to mark an object’s state as transient. In Hibernate, when an object is transient, it means that it is not associated with any database table.

When a transient mapped object is passed to Session‘s save method in Hibernate, the effect is that the object becomes persistent. The save method is used to save the state of the object to the database. If the object is transient, Hibernate will perform an INSERT operation in the database to create a new record with the object’s state.

Here’s a brief explanation of the terms:

Transient: An object in a transient state is not associated with any database table and has no representation in the database.
Persistent: An object in a persistent state is associated with a database table, and any changes made to the object will be synchronized with the database when the transaction is committed.

So, when you pass a transient mapped object to Session‘s save method, it transitions from being transient to becoming persistent, and its state is stored in the database.
