How to remove the first number from a queue?

Question

Hi,
I am trying to implement the following code for a queue. I've made an attempt on the RemoveFromQueue method, but it doesn't seem to work. How would i correctly be able the method for it to be able to remove the first number from the queue? thanks.
  if (q.QueueIsEmpty())
        System.out.println("Queue empty");
  else
         int firstEntry = q.RemoveFromQueue();     
              System.out.println("Integer extracted  : "  + firstEntry);
int RemoveFromQueue ()
         if (QueueIsEmpty())
               return false;
         else
              for(i=1; i <= total; i++)
                    Queue[i-1] = Queue;
                     total--;
                     return -1;
}

Answer 1

int RemoveFromQueue ()
if (QueueIsEmpty())
return false;
     else
     for(i=1; i <= total; i++)
     Queue[i-1] = Queue;
     total--;
     return -1;
}Here we go:
1) if the queue is empty you attempt to return 'false' while the method itself is
supposed to return an int.
2) you attempt to assign an entire queue to a single queue element.
3) your indentation is a mess.
4) why do you test for an empty queue outside of that method?
5) use pencil and paper and scribble down exactly what you want to do.
6) don't use initial uppercase letters for method names.
kind regards,
