How to reduce the number of variables in the signature of method in child class? Java refactoring

I have an abstract class A which does the main work, and also there are classes B and C which extend class A and implements the method doTheFinalMove().

public abstract class A {

    public Object aMethod() {
        Integer var1 = calculateVar1();
        String var2 = calculateVar2();
        Boolean var3 = calculateVar3();
        Object var4 = calculateVar4();
        Object var5 = calculateVar5();

        return doTheFinalMove(var1,
                var2,
                var3,
                var4,
                var5
        );
    }

    protected abstract Object doTheFinalMove(Integer var1,
                                             String var2,
                                             Boolean var3,
                                             Object var4,
                                             Object var5);

}

public class B extends A {

    @Override
    protected Object doTheFinalMove(Integer var1,
                                    String var2,
                                    Boolean var3,
                                    Object var4,
                                    Object var5) {
        return doMyStaff(
                var1,
                var2,
                var3,
                var4,
                var5);
    }
}

public class C extends A {

    @Override
    protected Object doTheFinalMove(Integer var1,
                                    String var2,
                                    Boolean var3,
                                    Object var4,
                                    Object var5) {
        return doMyStaff(var1, var2);
    }
}

So, class C unlike class B needs only two of the five variables to do its job, but in order to keep the inheritance of the class A, I should use all the five variables in the signature of doTheFinalMove() in A and C classes. I would like to refactor this code in the way that class C keep in its signature only those variables that it really needs (var1 and var2). I want to avoid using Object... args stuff, so I thought about wrapping these variables into an Object(I mean some inheritance like BasicParams and ExtendedParams) and then using an AbstractFactory or smth like that, but I don't know how to do it properly. I would be grateful for any advice.
