Difference between save and saveOrUpdate methods in Hibernate

In Hibernate, the save method is used to insert a new record into the database, while the saveOrUpdate method can be used for both saving a new object and updating an existing object. When using the save method, if the object is already present in the database, an exception will be thrown. On the other hand, the saveOrUpdate method checks if an object already exists in the database and decides whether to save it as a new record or update the existing one.

Overall, the save method is used specifically for inserting new records, whereas the saveOrUpdate method provides more flexibility for handling both new and existing objects in Hibernate.
