values in queue Java

Question

If I have a queue with strings as values How would I print all the values I was using:

System.out.println(queue.elements().toString().); 

But it prints java objects...?

Do I have to use a loop to print values of queue?

Answer 1

Yes, you will need to use a loop however the loop can be simple like.

for(String s : queue) { 
  System.out.println(s.toString()); 
}

Actually, as long as it implements Iterable you should be able to do this type of foreach loop.
