ThreadPoolExecutor- Thread termination

Question

I created a thread pool executor and submitted some callable tasks to thread pool and waiting on future object in the method futureobject.get(timeout, TimeUnit.SECONDS).
Once it is timed out i am catching the TimeoutException and cancelling the task through future.cancel(ture),
But it is just interrupting the thread and not cancelling the task if the task has already started executing.
Is there any way to stop the future Object task after a certain time out irrespective of its current state?
I want to terminate the thread execution and make the thread pick another task once if it is timed out.
One way is to interrupt the thread which is handling the future object task and then stop the thread.
Is there any other way that I can cancel a future Object task directly without dealing with the thread handling this future object task.
Can you throw a light on this. Any idea would be helpful...!!
Thanks in advance.

Thanks Peter for your reply.
But the problem is the thread is not like executing in a while loop to test every time whether it is interrupted or not by future.cancel(ture).
As my callable task is calling internally more methods which are call some more methods of other classes in this i cant put every where this logic to check whether thread is interrupted or not.
Even i have done that my concern is what if thread is executing a method long time because of some blocking problem. i need to wait the control comes back after method to check whether thread is interrupted or not. which is not desired..
let me put in an example.
public Object call(){
new ArrayList list=SampleClass1Object.readData();
// check whether thread is interrupt by future.cancel() method
Object ob= SampleClass2Object.display(list);
return ob;
If i fix time in future.get(timeout,TimeUnit). when the time out is happend the thread executing the method readData() it wont reflect immediately once this readData() method is completed then only it will check whether the thread is interrupted or not. This what is happening right now in my case.
