Does a fake data generator exists in Java? [closed]

Question

I would like to know if a fake data generator exists for Java. In Perl exists Data::Faker and there's a port to Ruby called faker, for JavaScript faker.js. Someone know about a fake data generator for Java, that can provide random names, phone number, P.O. box number, etc...

Answer 1

Try jFairy. This is new project in early stage.

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

System.out.println(person.fullName());            // Chloe Barker
System.out.println(person.email());               // [email protected]
System.out.println(person.telephoneNumber());     // 690-950-802

Company company = fairy.company();
System.out.println(company.name());          // Robuten Associates
System.out.println(company.url());           // http://www.robuteniaassociates.com

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

           String name = df.getFirstName() + " "+ df.getLastName();
           System.out.println(name);
