java - 线程监听器通知

Question

我在处理线程完成的类时遇到问题。它应该通知其他线程已完成，以便第二个线程可以启动。这是我的项目结构:

主类.java

public class MainClass implements ThreadCompleteListener {

public void main(String[] args) throws InterruptedException {

    NotifyingThread test = new Thread1();
    test.addListener((ThreadCompleteListener) this); 
    test.start();         

}

@Override
public void notifyOfThreadComplete(Thread thread) {
    // TODO Auto-generated method stub

}   

}

类 - Thread1.java

public class Thread1 extends NotifyingThread {

@Override
public void doRun() {
    try {
        metoda();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public static synchronized void metoda() throws InterruptedException {
    for(int i = 0; i <= 3; i++) {
        Thread.sleep(500);
        System.out.println("method in Thread1");
    }
}

public void notifyOfThreadComplete(Thread thread) {
    // TODO Auto-generated method stub

}
}

NotifyingThread.java

import java.util.Set;
import java.util.concurrent.CopyOnWriteArraySet;

public abstract class NotifyingThread extends Thread {
  private final Set<ThreadCompleteListener> listeners = new  CopyOnWriteArraySet<ThreadCompleteListener>();
  public final void addListener(final ThreadCompleteListener listener) {
    listeners.add(listener);
  }

  public final void removeListener(final ThreadCompleteListener listener) {
    listeners.remove(listener);
  }

  private final void notifyListeners() {
    for (ThreadCompleteListener listener : listeners) {
      listener.notifyOfThreadComplete(this);
    }
  }

  @Override
  public final void run() {
    try {
      doRun();
    } finally {
      notifyListeners();
    }
  }

  public abstract void doRun();
}

ThreadCompleteListener.java

public interface ThreadCompleteListener {
void notifyOfThreadComplete(final Thread thread);
}

我面临的问题是，当我执行 MainClass 时，我收到类似以下的错误:发生致命异常。程序将退出并在控制台中出现:

java.lang.NoSuchMethodError: 主要线程“main”中的异常

任何人都可以帮助在一次工作和平中实现这一目标，或者告诉我我在代码中做错了什么吗？

非常感谢任何建议!

替换 public void main

与public static void main
