I'm having trouble assigning a limit to the size of my double ended queue (Deque). It seems that my queue never gets full and just resizes whenever I add or offer a value unto it. My simple code just accepts a string value, splits it by space " ", loops everything and adds it to the queue.

```
evaluate("A B C D E F");

public static int evaluate(final String input){
    final Deque<String> stack = new ArrayDeque<>(3);
    final String[] tokens = input.split(" ");

    for (String token:tokens){
        System.out.println(stack.offer(token));
    }

    System.out.println(stack.size());
 }

```

returns:

```
 true
 true
 true
 true
 true
 true
 6

```

I was expecting that the queue will be full since I have not removed or read any value from it. Is there something that I'm missing here? Or am I just using the queue wrong? Thanks!
