. Production here is to take the wake of consumption, wake up is the consumption of the thread.If it is two locks, then the production can only be used for production, consumption can only be used for consumption (this is said in the previous practice), they can both run at the same time, will cause problems.And we now produce inside in the operation of time, consumption is not moving, this is called the same lock.Producer_con producer Monitor, Consum

Remember the first time to do the Java problem, see "write producer consumer problems", but also think it is related to the factory model. Now it is thunder to think about it.Java's producer consumer problem is the multi-threaded concurrent operation of the same resource buffer, when the resource buffer is full, the thread continues to add data, you should make i

Thread communication example-producer consumer issuesThis kind of problem describes a situation, assume that the warehouse can only store one product, the producer will produce the product into the warehouse, the consumer will take away the product of the warehouse. Assuming there is no product in the warehouse, the producer can put the product into the warehouse
