Code:java

try{
int hello = (Integer) Integer.parseInt(<String Message>);
//Code if is a number area above parses
//a String as an interger so "65" will return 65
}catch(Exception e)
{
//Code if it isn't a number
}

Hope it helped

 

PHP:

 try {
              int n = Integer.parseInt(string); // String could be args[0] or something
              //Do your method
              } catch (NumberFormatException e) {
              //If the string (as mentioned before could be args[0]) has letters in it,
              //which means that it can't be an integer since there is no numbers in integers.
              //So if it isn't an int
                }
