Can you describe the stages of an object's lifecycle in Hibernate?

The lifecycle of an object in Hibernate includes several main states:

1. Transient — the object is created in memory but not associated with a Hibernate session and not saved to the database.
2. Persistent — the object is associated with a Hibernate session and is being tracked; changes will be synchronized with the database upon commit.
3. Detached — the object was associated with a session, but the session is closed or the object is detached; changes will not be automatically saved.
4. Removed — the object is marked for deletion from the database upon the next commit.

Transitions between states occur through session methods such as save(), update(), delete(), evict(), etc.
