JoinAndForkUtility

Utility class to easily use join and fork feature from java 7.

Easy to use and improve performance for time consuming for loops.

It is more of an attempt to decouple fork/join/compute method etc etc from the business problem.

Usages

If you have to loop over time consuming method [ say List compute] for lots of objects [say class BusinessProblem].

Steps

1. Create an adaptor for BusinessProblem which implements ProblemSolution<List

2. Invoke Map<String,SolutionType> ForkAndJoinLoopUtil.solve(AdaptorToYourProblem);

It is as simple as that.

Examples
