5. 22. 6. The keyword super represents an instance of the direct superclass of the current object.

You can explicitly call the parent's constructor from a subclass's constructor by using the super keyword.
'super' must be the first statement in the constructor.


class Parent {

       public Parent(){

       

       }

     }



     public class Child extends Parent {

         public Child () {

           super();

         }

     }
