Method Overriding : Inheritance « Class Definition « Java Tutorial

  1. When you extends a class, you can change the behavior of a method in the parent class.
  2. This is called method overriding.
  3. This happens when you write in a subclass a method that has the same signature as a method in the parent class.
  4. If only the name is the same but the list of arguments is not, then it is method overloading.
