Examples of java.util.Random.nextBytes()

java.util.Random.nextBytes()
Generates random bytes and places them into a user-supplied byte array. The number of random bytes produced is equal to the length of the byte array.
The method {@code nextBytes} is implemented by class {@code Random}as if by:
```
  {@code}public void nextBytes(byte[] bytes)  for (int i = 0; i < bytes.length; ) for (int rnd = nextInt(), n = Math.min(bytes.length - i, 4); n-- > 0; rnd >>= 8) bytes[i++] = (byte)rnd; }}
```
@param bytes the byte array to fill with random bytes @throws NullPointerException if the byte array is null @since 1.1

      Random rand = new Random();
      params.put("millis", Math.abs(rand.nextLong()) % 1000);
      int payloadSize = Math.abs(rand.nextInt()) % 10000;
      byte[] payload = new byte[payloadSize];
      rand.nextBytes(payload);
      params.put("data", ByteBuffer.wrap(payload));
      req.request("sleep", params);
    }
  }
