Access Modifiers of Classes - I
Possible ClassModifiers are:
- abstract -- Contains abstract methods without implementation -- typically such abstract classes have several subclasses that define implementation of methods
- public -- May be used by code outside the class package and (unix) file must be called ClassName.java where ClassName is unique public class in file
- private -- this class can only be used within current file friendly(i.e. empty ClassModifier) -- class can be used only within current package
- protected -- Only accessible to subclasses
