How to use addKeyListener in a program running using command prompt

Question

Does anyone have any idea how to add the addKeyListener to a program running using command prompt.
Let me explain how the program run.
The program is start and accept call from other program. But from time to time, I need to issue some command by pressing the keyboard, let say, ESC is closed the program, F1 is showing the stated. F2.... (This is all need to run in the command prompt windows)
My problem is this program does not have any gui interface, so how can it be added?
i do it this way
public void key(){          
addKeyListener(this);
But it have compile error.
mainServerImpl.java:87: cannot resolve symbol
symbol : method addKeyListener (mainServerImpl)
location: class mainServerImpl
addKeyListener(this);
I did implement KeyListener. But just don't know how to solve this error.
can anyone tell me how to solve it or point me a source that can help.
Thank in advance!

Write your own Thread, to do this:
public class KeyThread extends Thread {
   public void run {
      while(true) {
         int i = System.in.read();
         if(i == 123) {
            break; // to stop the thread
// in your main:
Thread keyThread = new KeyThread();
keyThread.start(); // calls run() of the thread
