connect ftp from java program

Hi, I need to connect to the ftp and get the files through a java program.. I wrote the following code...

import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPFile;
import org.apache.commons.io.FileUtils;
import java.io.IOException;
public class FtpTest {
  public static void main(String[] args) {

   try{
    FTPClient client = new FTPClient();

    client.connect("ftp://111.111.111.111/");

    client.disconnect();

   }
   catch(Exception e){
    e.printStackTrace();
   }

  }
}

I have given a different ip than the above... But its not connecting... It shows me a runtime exception of UnknownHostException..

java.net.UnknownHostException: ftp://111.111.111.111/
