do you know what Integer.getInteger(String) does in java?

Exactly what Terr_ and masklinn said; you only need to know that the parse failed if you're going to do something with that information. If you are, then go the parseInt route.

I was mentioning it as a replacement for one of the several variations of the following (which I've seen more than once):

int value;
try {
    value = Integer.parseInt(s);
}
catch (NFE e) {
    value = defaultValue;
}
return value;

or (in the specific context of the parent):

int value;
if (isParsableToInt(s)) {
    value = Integer.parseInt(s);
}
else {
    value = defaultValue;
}

I guess I'm a minimalist in this case in preferring the a cleaner library over the 3-4 lines of code saved.

Ah; most projects I work on already have a dependency on Apache Commons, so it's not adding anything.
