Java并发程序设计(9)线程池之获取任务执行结果

ExecutorService  executorService = Executors.newFixedThreadPool(2);

Future<Integer>  future = executorService.submit( new Callable(){

 

@Override

public Integer  call() throws Exception {

return 1;

}

 

 

});

 

try {

int  ret = future.get();

System.out.println("return:" + ret);

} catch (InterruptedException e) {

e.printStackTrace();

} catch (ExecutionException e) {

e.printStackTrace();

}
