I just downloaded the sqldeveloper for Oracle vers.12c, but i do not have any Listener or TNS file. I can not find it in my computer or anywhere. And I need them for the preparation of the Oracel certification
How can I get them?

What you need is a database. Do you have it? If not, you'll have to download & install it. It contains files you need.
