A Java String to int conversion example

Here's a little Java code sample that shows how to try to perform a Java String to int conversion. In this example, if the conversion works, the variable pageNum will hold the int version of the pageNumString. If the conversion doesn't work a NumberFormatException will be thrown, and you'll need to deal with that.

String pageNumString = "5";
int pageNum = 0;
  // perform the string to int conversion here
  pageNum = Integer.parseInt(pageNumString);
catch (NumberFormatException nfe)
  // do something with the exception

Because pageNumString is 5, this particular String to int conversion will work, but if the string was "five" you'll get yourself a real nice exception. :)
