java - How to make a Thread from its ExecutorService communicate with a Runnable? -

i'm using executorservice parsing files:

executorservice service = executors.newfixedthreadpool(10); 

and later:

service.submit(new fileparser(file)); 

however tools used parse files require initialization takes quite long. i'd perform initialization once per thread (not once because initialization parameters not thread-safe), , perform parsing in submitted runnable.

i saw threadfactory can used provide own threads executor, initialize parameters way:

public class mythreadfactory implements threadfactory {     public thread newthread(runnable r) {         return new mythread(); // initialization part inside constructor     } } 

however have no idea on how provide new file parse thread... idea?

thanks

you can use threadlocal variable initialization. during each execution, can check if have executed initialization current thread , use storing whatever need.
