Write a java program to implement producer consumer problem

The steps to do the consumption of the item produced in independent and not dependent on other items. Explore, test and combine our data quality APIs at Melissa Developer Portal — home to tools that save time and boost revenue.

The definition if Item is as follows: To understand how this is possible, imagine how the procedure putItemIntoBuffer can be implemented.

In the solution below we use two semaphores, fillCount and emptyCount, to solve the problem. As a bonus for reading the post I put forward a test program that demonstrates how to use the above classes: The consumer takes the job from the buffer. Feel free to use it and twist it in whatever way you want.

Also, these variables stay incremented all the time; the relation remains correct when their values wrap around on an integer overflow. Both the processes work concurrently.

Producer Consumer Problem in C

When sleep is called, the caller is blocked until another process wakes it up by using the wakeup routine. Using monitors[ edit ] The following pseudo code shows a solution to the producer—consumer problem using monitors.

Having laid out the rules let us take a look at the consumer contract: Just before calling sleep, the consumer is interrupted and the producer is resumed. If the producer tries to decrement emptyCount when its value is zero, the producer is put to sleep.

In other words, the solution shown below works with any number of producers and consumers without any modifications. Consider the following scenario: Since both processes will sleep forever, we have run into a deadlock. This is because the consumer is only awakened by the producer when itemCount is equal to 1.

But there may be situations where the producer produce and tries to put an item into a full buffer. Once the production of new items is done the producer s will let the consumers know so that the consumer will exit after the last item is consumed and processed.

Solving a Producer-Consumer Problem in Java

There can be multiple producer. The producer creates an item, puts it into the buffer, and increases itemCount. It is interesting to note that to solve this problem at a generic level we can address only the consumer side and not the producer side. This setup makes sense in two cases: Consider the case where producer reads a line from a file and the "consumption and processing" is just to log the line in a special format back to a file then the use of a producer consumer problem solution can be considered a case of over-engineering a solution.

Producer Consumer Problem In C

The producer-consumer problem is one of the most frequently encountered problems when we attempt multi threaded programming. Produced items will be left unconsumed, starting items will be skipped, consumption depends on whether the production began earlier or later than consumption attempts etc.
