| |
− | ** Used to create superclasses comprised of common attributes (instance variables) and behaviors (methods)
| |
− | ** extends keyword - subclasses inherit all things public from the super class (except for constructors)
| |
− | ** super() - method can be used to call any of the superclass's constructors (0 or more parameters can be used if it matches)
| |
− | * Class Hierarchies
| |
− | ** A superclass reference variables can reference a subclass object
| |
− | * Polymorphism - same method names but different ... (parameters or objects)
| |
− | ** Overriding methods - subclass method overriding superclass method of the same name
