PureOOFizzBuzz

This project was inspired by Elegant Objects by Yegor Bugayenko

PureOOFizzBuzz is a true object-oriented and immutable Java8 demo. Its key benefits, comparing to all others, include these seven fundamental principles:

1. not a single null (why NULL is bad?)
2. not a single public static method (why they are bad?)
3. not a single mutable class (why they are bad?)
4. not a single instanceof keyword, type casting, or reflection (why?)
5. not a single getter or setter (why?)
6. not a single new outside of secondary constructors
7. not a single Java primitive

Usage

FizzBuzz values cannot be accessed directly. Instead they can be printed to any Media.

You can implement Media however you like.

####Print to Collection Usage

TextCollection media = new TextCollection();
new FizzBuzz(100).print(media);
Collection<String> stringValues = media.strings();

####Print Range to Collection Usage

TextCollection media = new TextCollection();
new FizzBuzz(15, 50).print(media);
Collection<String> stringValues = media.strings();

####Print to Console Usage

new FizzBuzz(100).print(new SystemConsole());
