    Generates random bytes and places them into a user-supplied byte array.

  23. def nextDouble(): Double

    Returns the next pseudorandom, uniformly distributed double value between 0.

    Returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator's sequence.

  30. def nextString(length: Int): String

    Returns a pseudorandomly generated String.

    Returns a pseudorandomly generated String. This routine does not take any measures to preserve the randomness of the distribution in the face of factors like unicode's variable-length encoding, so please don't use this for anything important. It's primarily intended for generating test data.
