The program uses a random number generator to simulate our case. Random r = new Random(); boolean male = r.nextBoolean(); TheRandomclass is used to produce random numbers. ThenextBooleanmethod returns randomly a boolean value. if (male == true) { name = "Robert"; } If the boolean var...
To get random bytes, a caller simply passes an array of any length, which is then filled with random bytes:synchronized public void nextBytes(byte[] bytes) Generating Seed BytesIf desired, it is possible to invoke the generateSeed method to generate a given number of seed bytes (to seed ...
