- Study the scenario and complete the question(s) that follow: 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. In this task, you are required to write a Java program in NetBeans that implements Parallel programming using the Fork/Join framework. Your program should initially generate 15 million random numbers. This should be read into an array of doubles. Then it should make use of a method that uses this array to calculate the sum of these doubles. Your program should make use of the subclasses in the Fork/Join…arrow_forwardIn what kinds of situations is it helpful to employ dynamic scoping, and how may its effectiveness be improved?arrow_forwardWhat are the pros and cons of Java's implicit heap storage recovery compared to C++'s explicit recovery?
