android - Can we use single FutureTask with Executor with different purposes -


i used newsinglethreadexecutor executors

executor msessionexecutor = executors.newsinglethreadexecutor();

here future task returns list

futuretask<list<string>> listfuturetask = new futuretask<list<string>>(new callable<list<session>>() {         @override         public list<string> call() throws exception {          return getsessions();         }     });

for getting o/p using below code

msessionexecutor.execute(listfuturetask); list<string> sessions= listfuturetask.get();

so question can use same future task multiple time listfuturetask.get(); returns same value exist while running first task

so can use ?

 msessionexecutor.execute(listfuturetask);  msessionexecutor.execute(listfuturetask); ..

multiple times after calling listfuturetask.get(); updated list always
