Access Control and Inheritance

• We declared many fields of Body to be public; this is not always a good design idea.
• Four possible access control modifiers:
  • private - members declared private are accessible only in the class itself.
  • protected - accessible in the class itself, and are accessible to, and inheritable by, code in the same package, and code in subclasses.
  • public - accessible anywhere the class is accessible, and inherited by all subclasses.
    
  • package - members declared with no access modifier are accessible in the class itself and are accessible to, and inheritable by, code in the same package.
