Making an interrupt back to a class

How would I make a class an interrupt back to its initializing class. I could pass this in as an initial argument, but I don't want want the memory use of passing in the whole object just so it can access one method.

I'm not quite sure on the names, but what I think I want is an abstract class that allows me to define my interrupt method in the class when I make a new instance of it.

Thanks for the help.

Here is the code of what I was trying to do.

Code :

---

public abstract class InteruptCreator extends Thread 
{
	private boolean go = true;
	private int _time;
 
	public InteruptCreator(int time)
	{		
		_time = time;
		start();
	}
 
	public void run()
	{
		while (go)
		{
			try
			{
				sleep(_time);
				interupt();
			}
			catch(InterruptedException e){}
		}
	}
 
	public abstract void interupt();
}

---

Code :

---

public class Main 
{
	private String _hostAddress; // address of web-server including file name on host
	private int _updateTimeSecs; // amount of time between updates sent to web-server
	private InteruptCreator _interupt;
 
	public Main(String hostAddress, int updateTimeSecs)
	{
		_hostAddress = hostAddress;
		_updateTimeSecs = updateTimeSecs;
 
		// start interupt thread
		_interupt = new InteruptCreator(6000, ??? new something @Override???);
	}
}

Don't worry, only a reference to an existing object is passed, not the whole object.

Doing what you suggest uses next to no memory...java objects are passed as references (not as copies). Another tip: its better practice to implement Runnable rather than extending Thread

Hmm, ok. Thank you.
