public class SynchronizedRandomGenerator extends Object implements RandomGenerator
RandomGenerator implementation can be thread-safe if it
 is used through an instance of this class.
 This is achieved by enclosing calls to the methods of the actual
 generator inside the overridden synchronized methods of this
 class.| Constructor and Description | 
|---|
| SynchronizedRandomGenerator(RandomGenerator rng)Creates a synchronized wrapper for the given  RandomGeneratorinstance. | 
| Modifier and Type | Method and Description | 
|---|---|
| boolean | nextBoolean()Returns the next pseudorandom, uniformly distributed
  booleanvalue from this random number generator's
 sequence. | 
| void | nextBytes(byte[] bytes)Generates random bytes and places them into a user-supplied
 byte array. | 
| double | nextDouble()Returns the next pseudorandom, uniformly distributed
  doublevalue between0.0and1.0from this random number generator's sequence. | 
| float | nextFloat()Returns the next pseudorandom, uniformly distributed  floatvalue between0.0and1.0from this random
 number generator's sequence. | 
| double | nextGaussian()Returns the next pseudorandom, Gaussian ("normally") distributed
  doublevalue with mean0.0and standard
 deviation1.0from this random number generator's sequence. | 
| int | nextInt()Returns the next pseudorandom, uniformly distributed  intvalue from this random number generator's sequence. | 
| int | nextInt(int n)Returns a pseudorandom, uniformly distributed  intvalue
 between 0 (inclusive) and the specified value (exclusive), drawn from
 this random number generator's sequence. | 
| long | nextLong()Returns the next pseudorandom, uniformly distributed  longvalue from this random number generator's sequence. | 
| void | setSeed(int seed)Sets the seed of the underlying random number generator using an
  intseed. | 
| void | setSeed(int[] seed)Sets the seed of the underlying random number generator using an
  intarray seed. | 
| void | setSeed(long seed)Sets the seed of the underlying random number generator using a
  longseed. |
