This is one of the most frequently asked Hibernate interview questions, I have seen it several times. The key difference between the get() and load() method is that load() will throw an exception if an object with an id passed to them is not found, but get() will return null.
Another important difference is that load can return proxy without hitting the database unless required (when you access any attribute other than id) but get() always go to the database, so sometimes using load() can be faster than the get() method.
Use the load() method, if you know the object exists, and the get() method if you are not sure about the object's existence
