I want to implement this scenario: there is one product pooling, one producer and one comsumer.
The producer can produce the product ceaselessly and add the product to the end of the pooling queue.The comsumer can get the first product from queue and repeatly.If there is no product in queue,the consumer is waiting.When the producer put the product into the queue, if the queue is empty,it can notify the comsumer to get. In my opnion, if the comsumer is getting the product, the producer can put the product.
How can I implement such scenario?
