inheritance

Comment

- "is a" relationship
- All class extends `Object` class
- extended or derived class has same logic as base class (`public` and `protected`)
- Allows code re-use
- `protected` = access modifier that acts like public in a package
- `private` members are not inherited by subclasses / derived class
