Multi Thread

Hi guys,

I am writing a program that will use TCP to communicate to other program, and everything is working just fine. now I want to add second Thread into the my client class, and I am confused.
here is the snap shot of my existing code.

public class Client implements Runnable
{
protected Thread myThread;
public void start()
{
if(myThread==null) myThread=new Thread(this);
myThread.start();
}
public void stop(){... do something}
public void run(){
 while (myThread!=null)
 {
    talking to other program through TCPIP
  }
}

now I want to add second thread called timer into this class, is it doable?
if so, how does it work?

Thanks

Hi,

First of all, you could use java.util.Timer, it will handle threads for you.

You cannot create thread for different task using same implementation of Runnable (you need different run), so write another class TimerClient implements Runnable and create thread for it.

Its better to Make Threads as seprate classes Like Timer etc and in Client Class declare as many object as you need and every thread would be responsible to its operations..

I feel its not good to directly implementa runnable..

it could be

class WhatEverYouLike extends Thread{
   public void run(){
     //do something for whatever it is supposed to
   }
}

class Timer extends Thread{
  public void run(){
    //do something for timer
  }
}

class Client{
  protected WhatEverYouLike thread1;
  protected Timer thread2;
  //now you can write methods in the client to do the job
}

A raw idea.. rest ya can do urself.. it may help you in your client application..

I am totally understand the method of extend thread class.
say we have a class A implement runnable,
and in class A we will have a lot of object which is extend from Thread?
or class A will only be able to have just one object then have many instance of class A?
