Java 线程侦听器通知

我对处理线程完成的类有问题。它将通知其他已精加工的线程，以便第二个线程可以启动。这是我的项目结构：

MainClass.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

}   

}

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

}
}

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();
}

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

Class-Thread1.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

}   

}

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

}
}

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();
}

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

我面临的问题是，当我执行MainClass时，我得到了一个错误，比如：发生了致命的异常。程序将退出并在控制台中显示：

java.lang.NoSuchMethodError:main 线程“main”中出现异常

有谁能帮我在一次工作中做到这一点，或者告诉我在代码中做错了什么

非常感谢你的建议

更换公共真空主管道

---

使用public

static

void main

我认为您应该替换：

public void main(String[] args)

为了

---

当我用公共静态void main替换公共void main时，我不能使用test.addListener（（ThreadCompleteListener）this）；因为我知道它不能在静态上下文中使用，所以我发现。。。。你关于谷歌搜索框的建议非常有用。。。这是一个如此扩展的工具，不是吗@先生，您当然会出错！！您需要用

newmainclass（）替换
this
，

notifyOfThreadComplete为空。这不是错误的原因，但它不会像您预期的那样工作。
