如何从另一个 class 处理 object

Question

I'm not sure if it's actually possible, but let's assume I have two classes. One run endless loop inside Thread , another create instance of that class inside method main . So everything works well, but how can I dispose that instance in main and interrupt from executing Thread with endless loop. Here is an example:

public class Main {
 public static void main(String[] args){
  new ThreadClass();
{
public class ThreadClass{
 public ThreadClass{
  try{
   Thread t = new Thread(new Runnable(){
    int i = 0;
    public void run(){
     while(true){
      i += 1;
      System.out.println(i);
      }
    }
  });
  t.start();
  }catch(Exception e){
   System.out.println("something ");
  }
 }
}

Thanks in advance:)

ThreadClass has to expose a way (eg, a method) to tell the loop to terminate. (Typically that involves setting/clearing a volatile flag that the loop uses in its while .) Then main would use that method at...some appropriate time. It's not clear what time you'd want it to, but you'd keep a reference to the instance you created and when that time came, you'd use the method.
