Understanding the Difference between get() and load() Methods in Hibernate

In Hibernate, the get() and load() methods are both used to retrieve an object from the database based on its primary key. However, there are key differences between these two methods:

1. get(): The get() method directly hits the database and retrieves the object. It returns null if the object with the specified primary key is not found in the database.
2. load(): The load() method returns a proxy (a placeholder object) without hitting the database immediately. It only retrieves the actual object from the database when a method is called on the proxy object. If the object is not found in the database, it throws an exception.

When using the get() method, the object is fully initialized and loaded into memory immediately. On the other hand, the load() method can be more efficient in certain situations where the actual object data is not immediately needed.

It is essential to choose the appropriate method based on the requirements of your application to optimize the performance of database operations in Hibernate.
