Inheritance and Extended Classes

  • Extended classes are also known as subclasses.
  • Inheritance models the is-a relationship.
  • If class E is an extended class of class B, then any object of E can act-as an object of B.
  • Only single inheritance is allowed among classes.
  • All public and protected members of a super class are accessible in the extended classes.
  • All protected members are also accessible within the package.
