        Test.getMusteriler().add(this);
        Test.getHesaplar().add(hesap);
        Test.getMusteriveHesabi().put(this, this.getHesap());

        FileStore.addToTheFileConfig(this);
    }
public Yonetici(String kullaniciAdi, String tamAdSoyad, int sifre, Hesap hesap, int yetkiSeviyesi) {
        this.yetkiSeviyesi = yetkiSeviyesi;
        this.hesap = hesap;
        super(kullaniciAdi, tamAdSoyad, sifre);

        //uuid = new Random().nextInt(10000, 1000000);
        //str = "Ad soyad: " + getTamAdSoyad() + "\n" + "Kullanıcı adı: " + getKullaniciAdi() + "\n" + "Müşteri kimlik numarası: " + getUuid() + "\n" + "Hesap mevcut mu: " ;
        Test.getMusteriler().add(this);
        Test.getHesaplar().add(hesap);
        Test.getMusteriveHesabi().put(this, this.getHesap());

        FileStore.addToTheFileConfig(this);
    }
so i have this 2 constructors right here and Yonetici inherits from the Musteri class and in Yonetici class it enters super(); section when it gets into it i want to know what happens i actually dont want 
FileStore.addToFileConfig(this);
FileStore.addToFileConfig(this);
to work if its coming from Yonetici class' super(); section

you could add a check in the super constructor but practically, constructors shouldn't add the this object to other stuff, especially static variables or things like that

if(this instanceof Yonetici);
else FileStore.addToTheFileConfig(this);
if(this instanceof Yonetici);
else FileStore.addToTheFileConfig(this);
i did this there

if(something) doSomething();
if(something) doSomething();
means "call doSomething if something is true" However, if you add a semicolon like 
if(something); doSomething();
if(something); doSomething();
it's the same as 
if(something) { }
doSomething();
if(something) { }
doSomething();
so it basically runs the doSomething method regardless of the result of the condition

so you mean 'else' will be executed no matter what?

oh I didn't notce the else block but if you have something you don't want to do for subclasses, you should use a factory method instead of a public constructor
