import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
public class CallableDemo {public static void main(String[] args) throws InterruptedException, ExecutionException {//执行服务器ExecutorService es = Executors.newCachedThreadPool();Future<String> f = es.submit(new cDemo());System.out.println(f.get());}	
}
class cDemo implements Callable<String>{@Overridepublic String call() throws Exception {return "Tom";}	
}
