I have a String composed of a series of numbers and need to get an int value of the number, i.e., convert "7" to 7.  Figured out how to do it, am wondering if there is a simpler way.

String theInput = "5678";
int intTemp = Integer.parseInt(String.valueOf(theInput.charAt(2)));

gives me intTemp = 7;
