Java _ multithreading _ producer and consumer (concurrent collaboration), java producer
For multi-threaded programs, regardless of any programming language, producer and consumer models are the most classic. Just like learning every programming language, Hello World! Are the most classic examples.In fact, it should be

It simplifies development, you can write the consumer and producer independently or concurrently, it just needs to know who the shared object is

Java provides a set of APIs to support the interaction between threads. A set of APIs waiting to be notified in the object classWait ()Notify ()Notifyall ()It is important to note that you must never call the Wait () method outside of the loop. (Open a separate article to discuss) The following uses consumer and producer issues to demonstrate the use of the above API:Packagexiancheng;publicclasspc{publicsta
Introduction:The producer-consumer model of the operating system curriculum can be said to be the best example of learning concurrency. It is important to note that Java does not support processes and only supports multithreading. This article will explain Java concurrency in one of the simplest producer consumer model

production method produce () : When the warehouse is full, the producer thread Waits, A production line is required to wait for the consumer to consume the product, and after the producer thread has finished producing the product, all threads that synchronize the lock are awakened through Notifyall (), including "Consumer threads", what we call "notifying consumers to consume". for consumption method
resources are accessed at most one thread at any time. The Java language implements a full object in multithreaded programming and provides good support for synchronization mechanisms. There are four methods in Java that support synchronization, the first three of which are synchronous methods, and one is the pipe method.
(1) Wait ()/Notify () method
(2) await ()/signal () method
(3) Blockingqueue blocking

1. Production/consumer modelProduction/consumer issues are a very typical multithreaded problem, involving the "producer", "Consumer", "Warehouse" and "product". The relationship between them is as follows:(01) The producer will stop production only when the storage is not full and the warehouse is full.(02) Consumers can only consume goods when they are in stora
