nextLong
Gets the next random
Long
from the random number generator.
Generates a
Long
random value uniformly distributed between
Long.MIN_VALUE
and
Long.MAX_VALUE
(inclusive).

val sortedRandomLongs = randomLongs.sorted()
println(sortedRandomLongs)
//sampleEnd
}
Gets the next random non-negative
Long
from the random number generator less than the specified
until
bound.
Generates a
Long
random value uniformly distributed between
0
(inclusive) and the specified
until
bound (exclusive).
