We have a scenario where we want to decouple an application from a service works over the network. In this application a number of threads produce prices, and a single thread for the network must transmit the prices as they arrive. However, as we are consuming the incoming prices, if a new price for a specific item is received before the ... |

Run I run my application both threads block. The consumer blocks waiting to be notified. The Producer every time it carrys out an action calls notifyAll(), this does not wake up the consumer thread, I guess that even though it has called notifyAll it still has the lock. It only releases the lock on a wait. When it can no longer ... |

I am using an ArrayBlockingQueue. A producer loops over some data and inserts into the queue until end of data. The consumer 'takes' from the queue until it receives a shutdown(i.e. the producer is finished) and the queue is empty(i.e. it is done processing all entires in the queue) Producer pseudo code for (Data d : allData) { queue.put(d); } // ... |

Because the println statements are outside of the synchronized blocks there's no guarantee about the order they'll be executed in. The producer supplies a number, the consumer gets it, but both tasks are now free to run, so the producer could send the second number before the consumer has executed it's println. BTW don't do while(empty == true) You risk missing ... |
