random - Java: Randomly generate distinct names

Question

I need to generate 10,000 unique identifiers in Java. The identifiers should be a mixture of numbers and letters and less than 10 characters each. Any ideas? Built in libraries would be an extra plus.

Answer 1

I am answering this very late, but this is what really useful for new reader. This is a very simple and efficient way to get random VALID names. To do so, add maven repository in POM.xml

<dependency>
    <groupId>com.github.javafaker</groupId>
    <artifactId>javafaker</artifactId>
    <version>0.12</version>
</dependency>

And then use the Faker class as below in your Java code

Faker faker = new Faker();

String name = faker.name().fullName();
String firstName = faker.name().firstName();
String lastName = faker.name().lastName();

String streetAddress = faker.address().streetAddress();

Try printing the result using standard System.out.println();
