How to intercept Ctrl key - eg Ctrl E being pressed on Java console program

Hello

I am writing console programs and my program waits streaming in text input
from the screen. But I need a way for the user to abort - I thought Ctrl
E - but how can I know when Ctrl E has been pressed.

I am roughly doing this sort of thing:

import java.io.*;

public class blah
{
    public static void main(String[] args)
    {
        // declaration section:
 BufferedReader cin = null; // console input
 String conline;

        try
        {
     cin = new BufferedReader(new InputStreamReader(System.in));
     System.out.println("Enter strings to remove last character");

     System.out.println("waiting... Press Ctrl E to end session");
     while ((conline = cin.readLine()) != null)
     {
         // If Ctrl E detected abort - break out - BUT HOW???

  System.out.println("processing: " + conline);
      int len = conline.length();
      String strRemovedot = conline.substring(0,len-1);
      System.out.println(strRemovedot);

            }

     cin.close();

 }
 catch (IOException e)
 {
                System.err.println("IOException: " + e);
        }
     }
}
