Inheritance

• extends
• Superclass (base class, ancestor class, ascendant class,..)
• Subclass (derived class, descendant class,..)
• Subclass instance can call superclass method
• Members inherited: public or protected, not package (NOT constructors: not class members)
• Methods Overriding: access equal or more
• Assigning a subclass object to a superclass instance
• Variable shadowing (hiding, both exist, NOT overriding)
• Accessing shadowed member variable: super.vName
• Finalizers: must provide explicit superclass invocation for garbage collection
• final class: cannot be extended
• Object class inherited methods
