It doesn't make sense to speak of "Telnet connectivity in Java code". You might ask whether there is Telnet connectivity to some other machine - that depends on whether the other machine is set up to be a Telnet host, and whether there's a network connection to that machine that allows Telnet traffic to go through. You can test this using a Telnet client such as Apache Commons Net.

As in there is a web site run by us.There are several protocols used http,https,ftp,ftps,ssh.My requirement is it i should check for generic protocol connectivity using telnet in local pc
for example:
if(ftp.isConnected()){
SFTLogger.writeToTraceLog(className,SFTConstants.INFO,
methodName,
userId+SFTConstants.HYPHEN_SEPERATOR+userName,
transmitterID + SFTConstants.HYPHEN_SEPERATOR + transmitterName,
fileTrackingID,
"Disconnecting from FTP Server ",null);

So you'd attempt a Telnet connection and handle any exceptions accordingly.

Note that Telnet should no longer be used over connections that go through untrusted networks (in other words, the public internet, unless it's over a VPN). That's what SSH is for.
