Multithreading,Callable,FutureObject

How can I return two individual iterated Set<String> values in a same method to a Future object which is in main method? I'm using Callable since I have to return a set of string values and store them for furthur use.

If I understand the question, it would be the same when you want to return multiple values from any method. You can always create a wrapper class that holds any number of Set values and return that from your Callable.

private static class MultiSet {
   Set<Integer> set1;
   Set<Integer> set2;
}

private static class MyCallable implements Callable<MultiSet> {
    public MultiSet call() {
        ...
    }
}
