Question

Can I create a subclass which parent is dynamic? For example; on class A extends B code, can I change B according to a condition? If can I return it from a method what will be the method’s return type? I mean class A extends getClassAccToCondition() return type.

Answer 1

I decide to use a way like a variation of simple polymorphism with Factory pattern. It will work for me i think. Thanks for answers.

public class Main {
    public static I getClassBelongToCondition(boolean Condition) {
        if (Condition) {
            return new A();
        } else {
            return new C();
        }
    }

}

interface I {
}

class A extends B implements I {
}

class C extends D implements I {
}

class B {
}

class D {
}
