Convert from Queue to Array

Question

I want to change a queue containing numbers and operators into an ArrayList. I am coding in Java.

Currently my Queue is defined as follows:

Queue outputQueue = new LinkedList();

The queue currently contains the following data:

[1, 9, 3, /, 4, 3, -, 2, /, *, +]

I wish to do this mainly so i can use RPN to calculate the result of the calculation, and i need to be able to index elements in the array/

Is there a way to do this?

Thanks in advance for any help :)
