Why should I call super() in Java?

Question

I see an example from a book that I read about java:

public class A{
  public A(){
      System.out.println(\"A\");
   }
}

public class B extends A{
    public          


        

Answer 1

super(); is redundant and unneeded. However sometimes you want to or must call a specific super class constructor. In those situations you would need to use it with the appropriate parameters: super( params );
