title: ArrayList of Integers to one int?
body: <p>what would be the easiest way to convert an ArrayList of Integers to one int, with the 1st Integer in the list being the 1st number in the int, etc. in Java? </p>
  
  <p>For example an ArrayList of Integers: 1 4 6 7 8 3 8<br>
  becomes the int value 1467838</p>
