11,100 PointsCould you just override the method instead of making a constructor?
class Animal { String sound = "";
void makeSound () {
System.out.println(sound);
}
}
class Dog extends Animal { @Override void makeSound() { super.makeSound(); System.out.println("Bark"); }

UX Design Techdegree Graduate 22,796 PointsOverriding allows a subclass to provide an implementation of a method that is already declared on the superclass. Constructors are used for initializing Objects. So, in this case, @Override is the one applicable. See my code below.
class Animal {
String sound = "";
//constructor t= intialize String sound variable
public Animal(String sound){
this.sound = sound;
}
//superclass method
public void makeSound () {
System.out.println(sound);
}
}
class Dog extends Animal {
@Override
public void makeSound() {
super.makeSound();
//inner classes can access variable from the outer class
System.out.println(sound);
}
}
