load vs. get method

1. When object exists or not

• Only use the load() method if you are sure that the object exists.
• If you are not sure that the object exists, then use one of the get() methods.

2. Return value, if ID not found

• load() method will throw an exception if the unique ID is not found in the database.
• get() method will return null if the unique id is not found in the database.

3. Fetch technique

• load() just returns a proxy by default and database won’t be hit until the proxy is first invoked.
• get() will hit the database immediately.
