Creates a random string based on a variety of options, using default source of randomness.

May 11, 2024 - @Test public void givenUsingApache_whenGeneratingRandomAlphanumericString_thenCorrect() { String generatedString = RandomStringUtils.randomAlphanumeric(10); System.out.println(generatedString); } And there we have it, creating bounded and unbounded strings with either plain Java, a Java 8 variant, or the Apache Commons Library. Through different implementation methods, we were able to generate bound and unbound strings using plain Java, a Java 8 variant, or the Apache Commons Library. In these Java examples, we used java.util.Random, but one point worth mentioning is that it is not cryptographically secure.

Please note that the Apache Commons project provides a component dedicated to pseudo-random number generation, namely Commons RNG, that may be a better choice for applications with more stringent requirements (performance and/or correctness). ... RandomStringUtils instances should NOT be constructed in standard programming. Instead, the class should be used as RandomStringUtils.random(5);. This constructor is public to permit tools that require a JavaBean instance to operate.
