Have you ever wondered how IFs impact on your code? Avoid dangerous IFs and use Objects to build a code that is flexible, changeable and easily testable, and will help avoid a lot of headaches and weekends spent debugging! Share how to write effective code the easy way!
The goal of the Anti-IF Campaign is to raise awareness of the effective use of software design principles and practices, by first of all removing bad, dangerous IFs.
The goal of the Anti-IF Campaign is to raise awareness of effective use of software design principles and practices, first of all removing bad, dangerous IFs.
The Campaign accomplishes this by:
- Supporting free initiatives and holding free events
- Gathering supporters
- Sharing experiences on how to improve design effectiveness
The Campaign started in 2007 from Francesco Cirillo's idea:
"Lots of teams want to be agile, but have difficulty cutting down on code complexity. Let's begin with something concrete: Knowing how to use objects in such a way that enables developers to eliminate bad IFs, those that most often compromise software's flexibility and ability to evolve. Let's start with these!"
The inappropriate use of IFs is a clear source of increased complexity of a software system. And this has consequences not only on developers' work. All the team can benefit a greater effectiveness by adopting the Anti-IF method.

about a developer working in a software company who was building up a nice platform. One day the boss calls the developer on the phone and says: "There’s a new task I need you to do for a really important client, and it must be done by the end of the day. All that’s needed," the boss continues "is to add a small piece of functionality to that class method you’ve been working on... it shouldn’t be too complex..."
and that small class, edit by edit, grows into a small code monster: the more you feed it with IFs, the bigger it grows!
What follows below is a single class method taken from real code that is live on a server somewhere on the Internet right now. And this is just a "baby monster". The more you feed it, the bigger it grows!
public ArrayList eseguiAnalisi() {
ArrayList listaSegnalazioni = new ArrayList();
List domande = null;
List risposte = null;
Domanda domanda = null;
DAOReques req = new DAOReques();
DAOArea ar = new DAOArea();
ar.setIdQuestionario(getIdQuestionario());
boolean quizDomandaNonForzata = false; // warning 7
try {
//set Aree e
if (getArea() == 1) {
List aree = ar.getAree();
Area area = null;
for (int i = 0; i < aree.size(); i++) {
area = (Area) aree.get(i);
domande = req.getDomande(getIdQuestionario(),area.getIdArea());
if (domande != null) {
for (int j = 0; j < domande.size(); j++) {
domanda = (Domanda) domande.get(j);
risposte = req.getRisposteDomanda(getIdQuestionario(),domanda.getIdDomanda());
if (risposte != null)
domanda.setRisposte(risposte);
}
}
}
area.setDomandeArea(domande);
if (aree != null)
setAreeDomande(aree);
} //else {
// set ListaDomande
domande = req.getDomande(getIdQuestionario());
for (int i = 0; i < domande.size(); i++) {
domanda = (Domanda) domande.get(i);
risposte = req.getRisposteDomanda(getIdQuestionario(),domanda.getIdDomanda());
if (risposte != null)
domanda.setRisposte(risposte);
}
if (domande!=null)
setDomande(domande);
//}
} catch (DAOException de) {
de.printStackTrace();
}
Yes, it is.
And it happens everyday all over the web.
So, what can I do to help?
