Question

Step1- Write a Java program in Netbeans that implements parallel programming using the Fork/Join framework. The program should initially generate 15 million random numbers. This should be read into an array of doubles.

Step 2- Then it should make use of a method that uses this array to calculate the sum of these doubles.

Step 3-This program should make use of the subclasses in the Fork/Join Framework abd should also output the number of processors available.

Step 4 - Have a clear screenshoot of code in the IDE and a screenshot of the code running.

The Fork/Join Framework is used for parallel programming in Java. The Fork/Join Framework
when illustrated in form of a diagram resembles a fork, hence its name. A problem is divided
into nonoverlapping subproblems, which can be solved independently in parallel. The solutions
to all subproblems are then joined to obtain an overall solution for the problem. This is the
parallel implementation of the divide-and-conquer approach. In JDK 7's Fork/Join Framework,
a fork can be viewed as an independent task that runs on a thread.
