Hello I have worker pattern that uses ExecutorService to schedule Thread execution but getting stuck at some point when returning a value using Future.I have code snippet below:

ExecutorService threadPool = Executors.newFixedThreadPool(1); 
      for ( int i=1; i<4; i++ ) { 
        threadPool.submit(new JobImpl("Job ", i));

Now this passes job and i as job and jobNumber to JobImpl class:

public class JobImpl implements Runnable {

    public String job;
    public int jobNumber;
   ExecutorService executorService = Executors.newSingleThreadExecutor();
    public JobImpl( String job, int jobNumber ) {

        this.job = job;
        this.jobNumber = jobNumber;
    }
    public String getJob() {

        return this.job;
    }
    executorService.execute(new JobImpl(job,jobNumber){
    public void run(){
    String j =Integer.toString(jobNumber);
    Deque<String> jdeque = new LinkedList<String>();

        jdeque.add(job+j);      
    }
});
    Future future = executorService.submit(new JobImpl(jdeque){
    public JobImpl call() throws Exception {
        return jdeque;
    }
});

}
