Bad explanation.

Step 1 says "The Producer thread tests the condition (buffer is full or not) and confirms that it must wait (after finding buffer is full)"

And then Step 3 says "3. The Consumer thread calls the notify () method; this goes unheard since the Producer thread is not yet waiting."

Total contradiction. Step 1 says Producer must wait; but step 3 says Producer is not waiting. No better explanation than the original poor official JavaDoc.

This explanation does not follow the standard, compared to the other articles in this blog.
