load vs. get method

load() vs. get()

1. 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.

2. Fetch technique

• load() just returns a proxy or make a database hit if any other method than getId() is called
        - Lazy initialization ; offers better performance
• get() will initialize the full objects using n number of database hits, if object could not found in session cache.

3. Use case

• 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.
