Good morning,
I'm a Java programmer and I'm interested to know better the process of
implementing a specification.
I have some doubts about the process:
1 - In order to do the specification implementation I need to create a
common Java project in my prefered IDE?
2- In the JPA specification there is a interface called
javax.persistence.EntityManager. When I'm implementing this interface,
should I use some code of this Interface given by Oracle or I need to
create the code for this interface EntityManager by myself in my
project inside a package javax.persistence created by myself too? The
doubt's essence is if when I'm implementing a specification I should
use some code created and given by Oracle or if I should create all
code(including the interfaces) by myself.
I would appreciate a lot if you could just clarify this subjects to me.
I love Java and I want to understand deeply all about specifications.
Thank you very much.
