thread and returning a method from object

[ilteris kaplan]

Hello,
I have three different classes, one is main one is dataGet and the last one is crawler.

so dataGet extends thread and calls crawler from inside just to make sure main is not halted, but I am kind of clueless how I am going to call a method inside of crawler since it is only instantiated in dataGet class and I am trying to call this method from my main class.

What do you guys say about this situation?
Thank you in advance

Simply put, without access to a pointer (or reference) of a crawler class, you can't. If you want, you can make a list of all crawler classes, and store them in a static list of main:

import java.util.*;
public class main
{
  private static ArrayList crawlerList=new ArrayList();
  //...
  public static ArrayList getCrawlerList()
  {
    return crawlerList;
  }
}
 
//...
 
public class crawler
{
  public crawler(//...)
  {
    //...
    main.getCrawlerList().add(this);
  }
  //...
}

That's sort of a cop out, but it works.
