import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

class ThreadExample implements Callable{

    @Override
    public String call() throws Exception {
        // TODO Auto-generated method stub
        return "Ashish";
    }

}
public class FutureThreadExample {

    public static void main(String a[]) throws InterruptedException, ExecutionException {
        ExecutorService executorService=Executors.newFixedThreadPool(1);
        List >objList=new ArrayList>();
       for(int i=0;i<10;i++) {
            Future obj=executorService.submit(new ThreadExample());
            objList.add(obj);
       }
        for( Future fut:objList) {
            System.out.println(fut.get());
        }
        executorService.shutdown();
    }
