Random class methods in Java

java.util.Random

An instance of this class is used to generate a stream of pseudo-random numbers. The class uses a 48-bit seed, which is modified using a linear congruential formula.

Some methods of Random class.

doubles(): This method returns an effectively unlimited stream of pseudorandom double values, each between zero (inclusive) and one(exclusive).

doubles(long): This method returns a stream producing the given streamSize number of pseudorandom double values, each between zero(inclusive) and one (exclusive).

doubles(double, double): This method returns an effectively unlimited stream of pseudorandom double values, each conforming to the given origin (inclusive) and bound(exclusive).

doubles(long, double, double): This method returns a stream producing the given streamSize number of pseudorandom double values, each conforming to the given origin(inclusive) and bound (exclusive).

equals(Object): This method indicates whether some other object is "equal to" this one.

hashCode(): This method returns a hash code value for the object.

ints(): This method returns an effectively unlimited stream of pseudorandom int values.

ints(long): This method returns a stream producing the given streamSize number of pseudorandom int values.

ints(int, int): This method returns an effectively unlimited stream of pseudorandom int values, each conforming to the given origin (inclusive) and bound(exclusive).

ints(long, int, int): This method returns a stream producing the given streamSize number of pseudorandom int values, each conforming to the given origin (inclusive) and bound (exclusive).

longs(): This method returns an effectively unlimited stream of pseudorandom long values.

longs(long): This method returns a stream producing the given streamSize number of pseudorandom long values.

longs(long, long): This method returns an effectively unlimited stream of pseudorandom long values, each conforming to the given origin (inclusive) and bound(exclusive).

longs(long, long, long): This method returns a stream producing the given streamSize number of pseudorandom long, each conforming to the given origin(inclusive) and bound (exclusive).

nextBoolean(): This method returns the next pseudorandom, uniformly distributed boolean value from this random number generator sequence.

nextBytes(byte[]): This method generates random bytes and places them into a user-supplied byte array.

nextDouble(): This method returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator's sequence.

nextFloat(): This method returns the next pseudorandom, uniformly distributed float value between 0.0 and 1.0 from this random number generator's sequence.

nextGaussian(): This method 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.

nextInt(): This method returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence.

nextInt(int): This method returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive).

nextLong(): This method returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence.

setSeed(long): This method sets the seed of this random number generator using a single long seed.

toString(): This method returns a string representation of the object.
