Java network programming help

[KZWings]

I have my two programs here:

http://www.kzwings.com/java/Client2.java

http://www.kzwings.com/java/Server2.java

This is going to be simple for most of you, but i need to modify the client to allow the user to specify an IP address. I need to provide secure communications between the client and the server as well. A simple encryption and decryption method MAY have to be done. ANY HELP IS MUCH APPRECIATED, thanks!!

So instead of using the hard coded IP string "127.0.0.1" you take the String from the array of command line arguments passed into the main() method and pass it into the constructor of your class.

 // execute application
public static void main( String args[] )
{
   final Client2 application = new Client2( args[0]);

   application.runClient();
}

Then from there of course you need a member variable to store the String in the instance so you can use it later place of the hard coded string. Also just pass the String to the Socket constructor.

Socket( _strConnect, 5558);
