Execute list of runnables with time gap

Question

I have a problem to solve. in which i need to run list of runnable objects with some delay in each request execution.

Say for ex I have a list like below

List<MyReqObject> myReqObjects=new ArrayList<MyReqObject>();

and I have created an executor with X number of threads like below

ExecutorService execute=Executors.newFixedThreadPool(X)

now using execute.invokeAl(myReqObjects); i an trying to invoke all these requests...

but I should have a delay in between these. to achieve this I tried

ScheduledExecutorService scheduler =Executors.newScheduledThreadPool(1);
scheduler.scheduleAtFixedRate(myObject, 2, 7, SECONDS); 

but here I cannot send list as a argument so I can execute same request for 7 sec with delay of 2 sec...

so is there a way to solve my problem please suggest me

Answer 1

create a Timer:

Timer timer = new Timer();

if you need to run it once then:

timer.schedule(new TimerTask() {
   @Override
   public void run() {
   // Your code here
   }
}, 2*1000); 

to run repeatedly:

 timer.scheduleAtFixedRate(new TimerTask() {
   @Override
   public void run() {
   // Your code here
   }
}, 2*1000); 

see some coding examples for Timer and TimerTask here
