'How to get desired output from ForkJoinPool.commonPool().submit

Please consider the below existing code segment in the project.

ForkJoinPool.commonPool().submit(() -> updateActions(a, b, c));

public void updateActions(a, b, c){ --some implementation-- }

updateActions is a void method. I'm going to change it to output a Map<String, String> from it. I want to keep the parallel execution behavior as it is and get the map at the end of execution from that.

I modified the code as below but couldn't get any output from it.

ForkJoinTask<Map<String, String>> output = ForkJoinPool.commonPool().submit(() -> updateActions(a, b, c));

changed updateActions method is as below-->

public Map<String, String> updateActions(a, b, c){ --some implementation-- return map; }

How can I change my code according to this requirement?
