Using the super keyword is handy if you want another constructor in the superclass to be invoked. For example, you can modify the constructor in Sub to the following. public Sub(String s) super(s); Chapter 6: Inheritance 159

  • Calling a constructor from the another constructor of same class is known as Constructor chaining. The real purpose of Constructor Chaining is that you can pass parameters through a bunch of different constructors, but only have the initialization done in a single place.
  • If you don’t explicitly call super, the compiler inserts a call to the default constructor of the base class. In that case, the base class must have a default constructor. In that case, the base class must have a default constructor.
  • Any constructor in a subclass must explicitly use the super() call, with the appropriate arguments, to invoke a non-default constructor in the superclass. This is because the constructor in the subclass cannot rely on an implicit super() call to the
