java - Is there a way to call an unimplemented abstract method from a supertype? -

i using java library requires objects used awt event dispatch thread. create interface program using library. far have this.

public abstract class iprogram implements runnable {     public static void main(string[] args) {      }     public void run() {         start();     }     public abstract void start(); } 

in main method run whatever subclass made. example, if program:

public class myprogram implements iprogram {     public void start() {         //code run program here...     } } 

i run myprogram , have run runnable. possible? if is, put in main method of iprogram?

edit: call runnable use swingutilities.invokelater(new runnableimplementation());
