You are taking a statistics class, and your instructor has found a website claiming a weird conspiracy theory that M&M colors are rigged, and he has asked you to determine the frequency of M&M colors from data collected by an M&M color-determination robot.

Your task is to design and implement a set of classes that process a collection of Integer objects, corresponding to an M&M color. The integers are stored in a queue by a driver. In particular, the following code must compile error free and execute correctly on your implementation. You should use generic Queue class from Programming Assignment 1. Your queue must import no Java data structures.

public static void main(String[] args) { Queue collection = new Queue(); for (int index = 0; index < 10000; index++) { int mm = ((int) (Math.random() * 10000)) % 5; Integer integ = new Integer(mm); collection.enqueue(integ); } RequestProcessor processor = new RequestProcessor(collection); int numberOfThreads = 5; Thread[] threads = new Thread[numberOfThreads]; for (int index = 0; index < threads.length; index++) { threads[index] = new Thread(processor); threads[index].start(); } try { for (int index = 0; index < threads.length; index++) { threads[index].join(); } } catch(InterruptedException ie) { ie.printStackTrace(); } ThreadStatisticsSetup.print(); }

One possible output is:

Tabulator: 1 Count 1137 for color Red=20.695303967965053% Tabulator: 1 Count 1077 for color Brown=19.603203494721516% Tabulator: 1 Count 1090 for color Yellow=19.839825263924283% Tabulator: 1 Count 1094 for color Green=19.912631962140516% Tabulator: 1 Count 1096 for color Blue=19.949035311248636% Tabulator: 2 Count 232 for color Red=19.414225941422593% Tabulator: 2 Count 232 for color Brown=19.414225941422593% Tabulator: 2 Count 243 for color Yellow=20.334728033472803% Tabulator: 2 Count 216 for color Green=18.07531380753138% Tabulator: 2 Count 272 for color Blue=22.761506276150627% Tabulator: 3 Count 79 for color Red=21.066666666666666% Tabulator: 3 Count 82 for color Brown=21.866666666666667% Tabulator: 3 Count 76 for color Yellow=20.266666666666666% Tabulator: 3 Count 85 for color Green=22.666666666666668% Tabulator: 3 Count 53 for color Blue=14.133333333333333% Tabulator: 4 Count 550 for color Red=20.161290322580644% Tabulator: 4 Count 573 for color Brown=21.00439882697947% Tabulator: 4 Count 564 for color Yellow=20.674486803519063% Tabulator: 4 Count 501 for color Green=18.365102639296186% Tabulator: 4 Count 540 for color Blue=19.794721407624632% Tabulator: 5 Count 44 for color Red=21.153846153846153% Tabulator: 5 Count 45 for color Brown=21.634615384615383% Tabulator: 5 Count 44 for color Yellow=21.153846153846153% Tabulator: 5 Count 32 for color Green=15.384615384615385% Tabulator: 5 Count 43 for color Blue=20.673076923076923% ==Totals== Color Red composes 20.42% of the total Color Brown composes 20.09% of the total Color Yellow composes 20.17% of the total Color Green composes 19.28% of the total Color Blue composes 20.04% of the total

The program was run with 5 threads. There are 10000 M&Ms. The number of M&Ms and portion calculated by each tabulator are printed by the class ThreadStatisticsSetup. Each thread in the RequestProcessor class must use a lock before accessing the collection. The threads must be as concurrent as possible, within reason. Each thread must have its own private area to store the total and individual color count processed by it. This private area must be supplied by ThreadStatisticsSetup. Moreover, these private areas must be stored in a queue by ThreadStatisticsSetup, so that class can easily print the queue in response to the call ThreadStatisticsSetup.print(). The generic queue can be used both for the collection of colors and the collection of private areas. Each thread must dequeue a single M&M color from the collection, process the M&M by updating the sum for the color to which that M&M corresponds. Each thread must count the colors it dequeues, not enqueue individual colors for ThreadStatisticsSetup to count. The private data area for each thread must be a count of colors, not a queue of separate M&Ms.

Your program may either use ThreadLocal for counting on each thread, or it may use separate class instances. The lock must be held only where absolutely necessary. Code that uses locks to run almost entirely in a single thread will receive very few points. You should verify that your code behaves correctly by testing it with many more than the required number of M&Ms, verifying that the totals you produce make sense, and adding a brief delay using Thread.sleep(10) (which you should remove before submission), and printing messages outside of locked code to verify that threads run concurrently. You can determine the unique id of the thread that is running by making Thread.currentThread().getId() call. The code you submit does not need to print this information.

When printing the M&Ms, the following colors correspond to each integer:

0: Red 1: Brown 2: Yellow 3. Green 4. Blue
