Question: What is the difference between load() and get()?Answer: load() vs. get()load() :- Only use the load() method if you are sure that the object exists. load() method will throw an exception if the unique id is not found in the database. load() just returns a proxy by default and database won't be hit until the proxy is first invoked. get():- If you are not sure that the object exists, then use one of the get() methods. get() method will return null if the unique id is not found in the database. get() will hit the database immediately. |
