Creating a hibernate persistent class

As discussed in the Preface, the developer will be dealing with objects at every step of development. Also, when we use hibernate, we don't need to work on a core SQL query. Here, we will create a POJO (Plain Old Java Object) in Java, which represents a table in the database.
