I just installed Oracle 18c Express Edition and SQLDeveloper successfully on my Windows 10 Pro box. Through SQLDeveloper, I'm able to see the LISTENER_XE database, but while expanding it's asking username and password. I don't remember feeding the username and password during installation. So, could someone please help me with the following:
- What is the username and password for LISTENER_XE.
- After installation, I'm being shown the following screen with number of URLs, but none of these URLs work in browser. Am I missing something? What are these Urls for?

Kindly help.
