TīmeklisThe algorithms implemented by class Random use a protected utility method that on each invocation can supply up to 32 pseudorandomly generated bits. Many applications will find the method Math.random() simpler to use. Instances of java.util.Random are threadsafe. However, the concurrent use of the same java.util.Random instance … TīmeklisJava implementations must use all the algorithms shown here for the class Random, for the sake of absolute portability of Java code. However, subclasses of class Random are permitted to use other algorithms, so long as they adhere to the general contracts for all the methods.
