Usage

Creating simple objects:

Fairy fairy = Fairy.create();
Person person = fairy.person();

System.out.println(person.getFirstName());            
// Chloe Barker
System.out.println(person.getEmail());               
// [email protected]
System.out.println(person.getTelephoneNumber());     
// 690-950-802

Person adultMale = fairy.person(PersonProperties.male(), PersonProperties.minAge(21));
System.out.println(adultMale.isMale());           
// true
System.out.println(adultMale.getDateOfBirth());      
// at least 21 years earlier

Creating related objects:

Fairy fairy = Fairy.create();
Company company = fairy.company();
System.out.println(company.getName());          
// Robuten Associates
System.out.println(company.getUrl());           
// http://www.robuteniaassociates.com

Person salesman = fairy.person(PersonProperties.withCompany(company));
System.out.println(salesman.getFullName());     
// Juan Camacho
System.out.println(salesman.getCompanyEmail()); 
// [email protected]

Locale support:

Fairy enFairy = Fairy.create();                               
// Locale.ENGLISH is default
Fairy plFairy = Fairy.create(Locale.forLanguageTag("pl"));    
// Polish version

Illegal Characters in E-Mail addresses

Generated names should not be used verbatim in the construction of email addresses, because they can contain characters that are not allowed in email addresses.

Example: "Hugo Groß" leads to the German ß umlaut appearing in his email address.

End of support for Java 7?

Oracle plans to end releasing public updates for Java 7 in April 2015. We are considering to end support for Java 7 in jFairy along with it (jFairy versions released after that time would require Java 8+).

If you (as a jFairy user) have a good argument to keep support for Java 7 a little bit longer please say it in that issue.

Add locale for GE

An attempt to extend JFairy by the GE locale. Note 1: ISO-639 code for Georgian language is "ka". I preferred using the (country code) "ge" wherever possible. Note 2: I neither speak Georgian nor have any detailed knowledge of the country. The module is based just of information googled from the net.

Error

WARNING: An illegal reflective access operation has occurred

The problem seems to be that JFairy depends on these old versions:

<dependency>
  <groupId>com.google.inject</groupId>
  <artifactId>guice</artifactId>
  <version>4.2.0</version>
</dependency>
<dependency>
  <groupId>com.google.inject.extensions</groupId>
  <artifactId>guice-assistedinject</artifactId>
  <version>4.2.0</version>
</dependency>

Upgrading to latest version 5.0.1 have solved the problem

<dependency>
    <groupId>com.google.inject</groupId>
    <artifactId>guice</artifactId>
    <version>5.0.1</version>
</dependency>
<dependency>
    <groupId>com.google.inject.extensions</groupId>
    <artifactId>guice-assistedinject</artifactId>
    <version>5.0.1</version>
</dependency>

This Guice Issue confirms this problem.

I recommend updating to newest version for Guice and Guice Assisted Inject

SvAddressProvider never provides an apartment number

The SvAddressProvider always provides an empty string as apartment number: https://github.com/Devskiller/jfairy/blob/f4c6a92db82c0ec5d1d5a24fe62df542f492e744/src/main/java/com/devskiller/jfairy/producer/person/locale/sv/SvAddressProvider.java#L16-L19

baseProducer.randomInt(20) returns an int between 0 and 20 (both inclusive), so it will be never less than 0.
