Answer from AI

The super keyword in Java is used to refer to members (methods or fields) of the superclass from a subclass. It allows:

  • Calling the constructor of the parent class from the constructor of the child class.
  • Accessing methods or fields of the parent class if they are overridden in the child.

Example of using super:

class Animal {
    void sound() {
        System.out.println("Animal sound");
    }
}

class Dog extends Animal {
    void sound() {
        super.sound(); // call to superclass method
        System.out.println("Bark");
    }

    Dog() {
        super(); // call to superclass constructor
    }
}

Thus, super helps manage inheritance and overriding, providing access to the parent class's functionality.
