Why is super.super.method(); not allowed in Java?
If you have a class that derives from a class that derives from another is there anyway for me to call the super.super method and not the overri开发者_StackOverflow社区dden one?
class A{
public void some(){}
}
class B extends A{
public void some(){}
}
class C extends B{
public void some(){I want to call A.some();}
}
See: Why is super.super.method(); not allowed in Java?
@tgamblin is right but here is a workaround :
class A{
public void some(){ sharedCode() }
public final void someFromSuper(){ sharedCode() }
private void sharedCode() { //code in A.some() }
}
class B extends A{
@Override
public void some(){}
}
class C extends B{
@Override
public void some(){
//I want to call A.some();
someFromSuper();
}
}
Create a second version of your method in A that is final (not overridable) and call it from C.
This is actually a poor design, but sometimes needed and used inside JDK itself.
