protected Members

• public members of a superclass are accessible by all methods in the program.
• private members of a superclass are accessible only by methods of the superclass.
• This all or nothing choice is softened by a 3rd option: protected.
• protected members of a superclass can be accessed only by:
  • methods of the superclass;
  • methods of the subclasses;
  • methods in other classes in the same package (you don't need to know what a package is for this course).
• Subclass methods normally refer to public, protected, and friendly members of the superclass simply by using the member names.
• When a sublcass method overrides a superclass method, the superclass method can be accessed from the subclass by preceding the superclass method name with super. .

  public void init() {

super.init();
