Faker is a Java library that generates fake data for you. Whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you.
Faker is heavily inspired by Fzaninotto's faker library in php.

Import com.Tunes_Developers.Faker to access faker library classes and methods.Use a faker object to create and initialize the faker library. In the object specify the language and the country. If not specified the default language will be English and the default country will be Kenya. Use of Upper case letters will nor affect the operation of the library provided that the country and language is supported. Above is a list of languages and countries supported.
import com.Tunes_Developers.Faker;
public class TestFaker {
public static void main(String[] args) {
//Initialize an object of the faker class to access the methods
Faker faker = new Faker("English","Kenya");
System.out.println(faker.name());
}
}Above is a simple call to create a random name. Each call to faker.name() yields a different random name. The faker library is designed to simulate real world scenarios.
import com.Tunes_Developers.Faker;
public class TestFaker {
public static void main(String[] args) {
//Initialize an object of the faker class to access the methods
Faker faker = new Faker("English","Kenya");
for (int i=0;i<10;i++){
System.out.println(faker.name());
}

}
}The Base class provides a number of usefull functionality like generating random numbers, ascii characters or even alphabetic characters with a specified format. Assuming you need to create random admision numbers with this format "J17-5380-2014"
import com.Tunes_Developers.Faker;
public class TestFaker {
public static void main(String[] args) {
Faker faker = new Faker();
for(int i=0;i<10;i++) {
System.out.println(
faker.numerify("J##-####-201#","J29-9999-2017")
);
}
}
// J07-6940-2012

// J14-3870-2013
// J09-4835-2010
// J25-3439-2015
}The faker.numerfy(String format,String constrain) method has been used to simulate admision numbers with a specific format. The # is used in places where you wish to replace with a random digit. The constrain parameter is used to define the maximum admission number that can be generated. Here are some more functionalities of the base class.
randomDigit() // 3
digitBetween(5,9) // 5
randomLetter() // v
numerify("Hello ####") // Hello 4424
