    Oracle Sql Developer problem to create New Connection


      I have download oracle sql developer 32/64 bit package and export it into my G drive. I run the .exe file direct.

      I have tried so much times to create a new connection but each and every time "IO error the network adapter could not establish the connection sql developer" comes.

      I have tried to find solution online to fix this problem and online and I found that each and every solution says to modify the listener.ora and tnsnames.ora file. I am not finding these files in my computer C drive, G drive, sqldeveloper folder.

      What should I do.

      please help me for making a new connection in my oracle sql developer.


      Thanks in advance
