ThreadLocalRandom
public
final
class
ThreadLocalRandom
extends Random
A random number generator (with period 264) isolated
to the current thread. Like the global Random
generator used by the Math class,
a ThreadLocalRandom is initialized
with an internally generated seed that may not otherwise be
modified. When applicable, use of ThreadLocalRandom rather
than shared Random objects in concurrent programs will
typically encounter much less overhead and contention. Use of
ThreadLocalRandom is particularly appropriate when multiple
tasks (for example, each a ForkJoinTask) use random numbers
in parallel in thread pools.
Usages of this class should typically be of the form:
ThreadLocalRandom.current().nextX(...) (where
X is Int, Long, etc).
When all usages are of this form, it is never possible to
accidentally share a ThreadLocalRandom across multiple threads.
This class also provides additional commonly used bounded random
generation methods.
Instances of ThreadLocalRandom are not cryptographically
secure. Consider instead using SecureRandom
in security-sensitive applications. Additionally,
default-constructed instances do not use a cryptographically random
seed unless the system property
java.util.secureRandomSeed is set to true.
