PrimeFinder

For this homework, you will modify the work queue implementation and use it to find primes. Specifically, you must:

• Add a pending variable to the WorkQueue class to track unfinished work and implement a finish() method that waits until there is no more pending work. Use this new functionality in PrimeFinder; there should not be a pending variable or TaskManager nested class in the PrimeFinder class!

• Implement the multithreaded findPrimes(int, int, int) method in PrimeFinder using your modified WorkQueue class. There should be 1 task or Runnable object for each number being tested and the run() method of these objects should use the isPrime(int) method.

Hints

Below are some hints that may help with this homework assignment:

• If you move tracking of the pending variable into the WorkQueue class properly, there is no need to create a nested TaskManager class within the PrimeFinder class. You will need to create an inner "task" class, however.

• Do not try to use lambda expressions or streams here, since data must be mutated outside of a thread's scope.

These hints are optional. There may be multiple approaches to solving this homework.

Requirements

See the Javadoc and TODO comments in the template code in the src/main/java directory for additional details. You must pass the tests provided in the src/test/java directory. Do not modify any of the files in the src/test directory.

See the Homework Guides for additional details on homework requirements and submission.
