Java Thread NotifyAll Method

Chapter: Thread Last Updated: 07-08-2017 16:02:09 UTC

Program:

            /* ............... START ............... */
                public class Buffer {
  private List buffer = new ArrayList();

  public void addItem(V obj) {
    synchronized (buffer) {
      while (buffer.size() >= maxSize) {
        buffer.wait();
      }
      buffer.add(obj);
    }
  }

  public void clear() {
    synchronized (buffer) {
      buffer.clear();
      buffer.notifyAll();
    }
  }
}
                /* ............... END ............... */
        

Notes:

  • notifyAll() wakes up all the threads that called wait() on the same object. The highest priority thread will run first in most of the situation, though not guaranteed.
  • Synatax : public final void notifyAll()
