标题:
线程池笔试题.
开启十条线程，第一个1到10想加，第二个11到20想加，以次类推 得到结果并输出
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
public class Demo {
public static void main(String[] args) throws Exception, Exception {
ExecutorService es = Executors.newFixedThreadPool(10);
Future<Integer> f1 = es.submit(new MyCallable(1,10));
Future<Integer> f2 =es.submit(new MyCallable(11,20));
Future<Integer> f3 =es.submit(new MyCallable(21,30));
Future<Integer> f4 =es.submit(new MyCallable(31,40));
Future<Integer> f5 =es.submit(new MyCallable(41,50));
Future<Integer> f6 =es.submit(new MyCallable(51,60));
Future<Integer> f7 =es.submit(new MyCallable(61,70));
Future<Integer> f8 =es.submit(new MyCallable(71,80));
Future<Integer> f9 =es.submit(new MyCallable(81,90));
Future<Integer> f10 =es.submit(new MyCallable(91,100));
System.out.println(f1.get());

}
}
