All Implemented Interfaces:

Serializable, Future<Void>

public class RecursiveActionComparison
extends RecursiveAction

Parallel Array Transformation (Fork/Join)

Demonstrates the divide-and-conquer pattern utilizing RecursiveAction to mutate a shared array in-place. It calculates the mathematical cube root for each element, distributing the workload across multiple threads.

RecursiveActionComparison

public RecursiveActionComparison(int[] data,
 int start,
 int end,
 int threshold)

Initializes the parallel action for a specific segment of the array.

Parameters:

data - The shared array to be mutated in-place.

start - The inclusive starting index of the segment.

end - The exclusive ending index of the segment.

threshold - The granularity limit. Segments smaller than this are processed sequentially.
