sockets - How to listen on IP and Port in Java ? with ServerSocket? -

-

i'm creating client/server chat (multi-threading) app in java .

i want listen clients on specific port , ip .

when : 

serversocket serversocket = new serversocket(port); socket socket = serversocket.accept();      // accept connection  // more code

does mean ip i'm listening 127.0.0.1 ? i.e. localhost ?

from on constructor of serversocket object , have 3 types of constructors : 

public serversocket(int port) throws ioexception public serversocket(int port, int backlog) throws ioexception public serversocket(int port, int backlog, inetaddress bindaddr)  throws ioexception

what constructor should use , if want clients other ip addresses

this 1 : 

public serversocket(int port) throws ioexception

or 1 : 

public serversocket(int port, int backlog, inetaddress bindaddr)  throws ioexception

?

much appreciated

does mean ip i'm listening 127.0.0.1 ? i.e. localhost ?

no. means listening on ip addresses of host.

what constructor should use if want clients other ip addresses?

this one.
