def nextBoolean(): Boolean

Returns the next pseudorandom, uniformly distributed boolean value from this random number generator's sequence.
def nextBytes(bytes: Array[Byte]): Unit

Generates random bytes and places them into a user-supplied byte array.
def nextDouble(): Double

Returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator's sequence.
def nextFloat(): Float

Returns the next pseudorandom, uniformly distributed float value between 0.0 and 1.0 from this random number generator's sequence.
def nextGaussian(): Double

Returns the next pseudorandom, Gaussian ("normally") distributed double value with mean 0.0 and standard deviation 1.0 from this random number generator's sequence.
def nextInt(n: Int): Int

Returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn from this random number generator's sequence.
def nextInt(): Int

Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence.
def nextLong(): Long

Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence.
def nextPrintableChar(): Char

Returns the next pseudorandom, uniformly distributed value from the ASCII range 33-126.
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.
