How does inheritance work with constructors in Java?
An example of an AI chatbot conversation about inheritance and constructors in Java.
Can you explain how inheritance works with constructors in Java?
Sure! In Java, when a subclass is created, it inherits the properties and methods of its superclass, but constructors are not inherited.
So, how does the subclass call the constructor of the superclass?
The subclass can call the superclass constructor using the super() keyword, which must be the first line in the subclass constructor.
What happens if I don't call the superclass constructor?
If you don't explicitly call the superclass constructor, Java automatically calls the no-argument constructor of the superclass, if it exists.
Can you give me an example of this?
Certainly! If you have a superclass Animal with a constructor and a subclass Dog, you would use super() in Dog's constructor to call Animal's constructor.
