# Bank Kata
Your bank is tired of its mainframe COBOL accounting software and they hired both of you for a greenfield project in your favorite programming language!
Your task is to show them that your TDD-full and your new-age programming language can cope with good ole’ COBOL!
## Requirements
Write a class `Account` that offers the following methods:
* `void deposit(int)`
* `void withdraw(int)`
* `void printStatements()`
## The Rules
* One level of indentation per method
* Don’t use the ELSE keyword
* Wrap all primitives and Strings
* First class collections
* One dot per line (Follow de [Demeter Law)](https://en.wikipedia.org/wiki/Law_of_Demeter)
* Don’t abbreviate
* Keep all entities small (50 lines)
* No classes with more than two instance variables
* No getters/setters/properties
#### For more information: [Object Calisthenics PDF](http://www.cs.helsinki.fi/u/luontola/tdd-2009/ext/ObjectCalisthenics.pdf)
## Example
An example statement would be:
```bash
Date Amount Balance
24.12.2015 +500 500
23.8.2016 -100 400
```
