In many cases, it is a good idea to first use the trim() method to the
String to be parsed.

int number;
String s = getStringToBeParsed(); // whatever you do to get the input
if (s != null) {
    number = Integer.parseInt(s.trim());
} else {
    // what ever is the proper thing to do in the particular case
}
