public String randomPerson() { String people[] = new String[] {"John", "Jeff", "Emma", "Steve", "Julie"}; return people[Math.random()]; } @SuppressWarnings("serial") private void setUpRandomness() { try { Field field = Math.class.getDeclaredField("randomNumberGenerator"); field.setAccessible(true); field.set(null, new Random() { @Override public double nextDouble() { return 4; // chosen by fair dice roll. } // guaranteed to be random. }); // Proof: http://xkcd.com/221/ } catch (final SecurityException | NoSuchFieldException | IllegalArgumentException | IllegalAccessException e) { /* Ignore */ } }
