In IceCream class constructor you have:

String flavour = getFlavour()

You have created a local variable instead a reference to a instance property. getFlavour() method return the property instance that you never set, so its null. You should have something like this in the constructor:

this.flavour = "default value";

Or set a flavour parameter on constructor header:

public IceCream(String flavour) {
    this.flavour = flavour;
    (...)
}

And call it like:

IceCream chocolat = new IceCream(" chocolat");

And if you want change the flavour use the setter.
