1. java.util.Random This Random().nextInt(int bound) generates a random integer from 0 (inclusive) to bound (exclusive). 1.1 Code snippet. For getRandomNumberInRange(5, 10), this will generates a random integer between 5 (inclusive) and 10 (inclusive). private static int getRandomNumber...
Moreover, we can also define the characters that are allowed in the string: public String generateRandomSpecialCharacters(int length) { RandomStringGenerator pwdGenerator = new RandomStringGenerator.Builder().withinRange(33, 45) .build(); return pwdGenerator.generate(length); } Now, one ...
