Java Random class

Java Random class is used to generate a stream of pseudorandom numbers. The algorithms implemented by Random class use a protected utility method than can supply up to 32 pseudorandomly generated bits on each invocation.

Methods

Methods Description
doubles() Returns an unlimited stream of pseudorandom double values.
ints() Returns an unlimited stream of pseudorandom int values.
longs() Returns an unlimited stream of pseudorandom long values.
next() Generates the next pseudorandom number.
nextBoolean() Returns the next uniformly distributed pseudorandom boolean value from the random number generator's sequence
nextByte() Generates random bytes and puts them into a specified byte array.
nextDouble() Returns the next pseudorandom Double value between 0.0 and 1.0 from the random number generator's sequence
nextFloat() Returns the next uniformly distributed pseudorandom Float value between 0.0 and 1.0 from this random number generator's sequence
nextGaussian() Returns the next pseudorandom Gaussian double value with mean 0.0 and standard deviation 1.0 from this random number generator's sequence.
nextInt() Returns a uniformly distributed pseudorandom int value generated from this random number generator's sequence
nextLong() Returns the next uniformly distributed pseudorandom long value from the random number generator's sequence.
setSeed() Sets the seed of this random number generator using a single long seed.
