      Example:

      static void test1() { int n = (Integer.MAX_VALUE / 3) * 2; int bottom = 0; for (int i=0; i<1000000; i++) { if (generateRandom(n) < n/2) bottom++; } System.out.println(“bottom=” + bottom); }

      Example:

      Random r = new Random(); byte[] arr = new byte[100]; r.nextBytes(arr); for(int i = 0; i < arr.length; i++){ System.out.println(arr[i]); }

      Example:

      Random r = new Random(); int[] arr = new int[100]; for(int i = 0; i < arr.length; i++){ arr[i] = r.nextInt(); System.out.println(arr[i]); }
