Java_ Multithreading _ producer and Consumer (concurrent collaboration)

For multi-threaded programs, both the producer and consumer models are the most classic, regardless of the programming language. Just like learning every programming language, Hello world! Are the most classic examples.

In fact, it should be "producer-consumer-warehousing" model, leaving the warehouse, the producer consumer model is not convincing.
For this model, you should be clear about the points:
1, the producer only in the storage is not full time production, warehouse full stop production.
2, consumers only in storage products can be consumed, Cang is waiting.
3, when the consumer found that the storage of products can be consumed when the producers will be informed of production.
4, producers in the production of consumable products, should inform the waiting consumers to spend.
