Answer / Yatendra Kumar

Detached objects are Hibernate entities that have been detached from the session. Advantages include: 1) Flexibility as you can modify the object without affecting the database; 2) Reduced load on the database as changes are not saved immediately. Disadvantages include: 1) Changes to detached objects are not tracked, so differences between the original and modified object need to be handled manually before reattaching; 2) If you want to persist the changes, you'll have to save or update the object explicitly.

Will it be called overriding if I do not change the parameters or return type, instead throw a different exception in the method signature.
