Inheritance, Interface, Package

Source: Inheritance, Interface, Package

What is Inheritance?

- Inheritance allows the ability to *inherit* commonly used state and behavior from other classes.  
    Ex: Mountain bikes, road bikes, and tandem bikes all share characteristics of bicycle (current speed, current  
        pedal cadence, current gear)

What is Interface?

- Interface Methods form the object's interface with the outside world; the buttons on the front of your television  
set, for example, are the interface between you and the electrical wiring on the other side of its plastic casing  

What Is a Package?

- A package is a namespace that oganizes a set of related classes and interfaces. 
    Ex: Different folders on a computer.
