Part 1: Remembering how interfaces work

Interfaces are another way to achieve abstraction in Java and allow for multiple inheritance.
- Think of it as a blueprint for a set of behaviors, or a certification with a list of requirements
- Interfaces specify what a implementing class can do, not how.
- The Interface and Class should still follow a "Is-A" relationship
Interfaces Vs. Abstract Classes
- Interfaces do not have constructors, abstract classes do (whether its the null implicit constructor or explicitly declared constructor)
- Interfaces can only have abstract methods, abstract classes can have both concrete or abstract methods.
- Concrete classes can implement multiple interfaces, classes can only extend one abstract class

A class implementing Comparable means that it is capable of comparing itself with another object.
- 1 Required Method
  - compareTo() which returns a signed int.
A class implementing Comparator is capable of comparing two other objects, even if the objects don't implement comparable themselves.
- 1 Required Method
  - compare() which returns a signed int.
Complete TODOs 1.1 through 1.11 in the /Compara folder.

A class implementing Iterable represents a series of objects that can be iterated over.
- 1 Required Method
  - iterator() which returns an Iterator.
A class implementing Iterator is the object with iteration state.
- 2 Required Methods
  - hasNext() which returns a boolean representing whether the iterator has an element following the current one
  - next() which returns the next object to be iterated over.
Complete TODOs 2.x through 2.x in the /Itera folder.
