SQL developer- the network adapter could not establish the connection

I am new to oracle database and i was trying to set up SQL developer.After installation when I open it and make a new connection it gives me "IO error: the network adapter could not establish the connection".I tried to look up for the solution everywhere but nothing worked.Can someone please explain me in detail hoe to fix this thing?
You have installed SQL Developer, the client.
It's effectively limited to working with files and offline data models.
If you want to do database work, you need a database.
Here's your options for getting started.
You have to start the listener with
lsnrctl start

Issue with SQL Plus

I have a database that I am trying to connect to through SQL Plus. I run this command from the command line:
sqlplus username/password#//hostname:port/sid
I use this connection string instead of using tsnames. The error I keep getting is
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
The weird thing is that using the same connection information I can connect just fine through SQL Developer. I can see the tables, users, and everything else. Anyone know what could be going on?
P.S. I tried setting up tsnames but it just gave the same thing as using the connection string.
So my boss found the solution. Turns out the sid is different when connecting through SQL Plus then through SQL Developer. Seemingly in just this one case. I have no idea why this is but that was the reason. Very odd and I don't understand why.
