nextDouble()
Returns the next pseudorandom, uniformly distributed
double value between 0.0 and
1.0 from this random number generator's sequence. |
float |
nextFloat()
Returns the next pseudorandom, uniformly distributed
float
value between 0.0 and 1.0 from this random
number generator's sequence. |
double |
nextGaussian()
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. |
int |
nextInt()

int
value from this random number generator's sequence. |
int |
nextInt(int n)
Returns a pseudorandom, uniformly distributed
int value
between 0 (inclusive) and the specified value (exclusive), drawn from
this random number generator's sequence. |
long |
nextLong()
Returns the next pseudorandom, uniformly distributed
long
value from this random number generator's sequence. |

int seed. |
void |
setSeed(int[] seed)
Sets the seed of the underlying random number generator using an
int array seed. |
void |
setSeed(long seed)
Sets the seed of the underlying random number generator using a
long seed. |
