def randomIntBetween(low: Int, high: Int): Int

Return a random integer between low and high, inclusive.
Return a random integer between low and high, inclusive. If low and high are identical, low is returned.
low
the lowest number
high
the highest number
returns
an integer in the range [low, high].

def randomLongBetween(low: Long, high: Long): Long

Return a random long integer between low and high, inclusive.
Return a random long integer between low and high, inclusive. If low and high are identical, low is returned.
low

def randomString(length: Int, chars: String = DefaultRandomStringChars): String

Return a random string.
Return a random string. This method is similar to Random.nextString(), except that it allows you to control the set of characters that are allowed to be in the returned string. The set of characters defaults to ASCII alphanumerics.
length
the size of the string to return
chars
the set of legal characters
returns
a random string, drawn from the supplied characters, of the specified length
