Here is complete Java program to solve producer consumer problem in Java programming language.
In this program we have used wait and notify method from
Object class instead of using Blocking Queue for flow control.
to implement producer consumer design pattern is much better because of its simplicity and concise code.
Order: 9 being taken care of with 2 meals also ready.
Order: 4 being taken care of with 2 meals also ready.In the example above there clearly is a race, however this is not a race condition.In this case there are no errors due to the threads running out of order and thus there is no issue.In this Java tutorial, I have put the code example of wait notify version of earlier producer consumer concurrency design pattern.You can see this is much longer code with explicit handling blocking conditions like when shared queue is full and when queue is empty. If you see I have kept consumer thread little slow by allowing it to sleep for 50 Milli second to give an opportunity to producer to fill the queue, which helps to understand that Producer thread is also waiting when Queue is full.The easy way we can identify and reduce this problem to a producer-consumer problem is by identifying that we have a limited number of consumers and a infinite number of items being produced.This means we have to use a semaphore in order to keep track of how many produced items are currently being handled by consumers.Order: 10 being taken care of with 1 meals also ready.Order: 1 being taken care of with 0 meals also ready.The consumer will know when data entered into the buffer for consuming and producer must stop producing when consumption rate is slow and the buffer is filled.To solve producer consumer problem, We need to take care few things like producer stop producing by either go to sleep or discard data.
