super keyword in Java

• #The super variable refers to the direct parent class instance.
• Super variables can call direct parent class methods.
• super() acts as the direct parent class constructor and should be the first line in the child class constructor.

Use the super keyword when calling the superclass version of an overridden method.

Live Demonstration

   public void move() {
      System.out.println("Animals can move");
   }
}
class Dog extends Animal {
   public void move() {
      super.move(); // invokes the super class method
      System.out.println("Dogs can walk and run");
   }
}
public class TestDog {
   public static void main(String args[]) {
      Animal b = new Dog(); // Animal reference but Dog object
      b.move(); // runs the method in Dog class
   }
}
