Regain Access to Running Thread without passing reference

[Thomas Martin]

Howdy! my question is if I can regain access to a thread that is running from different classes without directly passing a reference?

Consider:

public class SomeThread extends Thread{
         public c = 0;
         public int getC(){
                   return c;
          }
        public void run(){
                while(true){
                        try{
                                System.out.println("count: "+c++);
                                sleep(1000);
                        }catch(InterruptedException e){
                                System.out.println(e);
                        }
                }
        }
}
public class A {
         public static void main(String[] args){
                   SomeThread st = new SomeThread();
                   st.start();
                   // save reference to file/db -------> HOW?
         }
}
public class B {
         public static void main(String[] args){
                   //retreive reference to initaited SomeThread object in class A -------> HOW?
                   int x = recoveredst.getC(); // assuming "recoveredst" is reference to SomeThread object instantiated in class A!
         }
}

Inputs highly appreciated!
Thanks, T.

You can always access the currently running Thread by doing Thread.currentThread(). In your case, I wouldn't extend Thread at all. Use a Runnable object instead.
