Uses of Class
java.util.Random

Packages that use Random
java.math	Provides classes for performing arbitrary-precision integer arithmetic (BigInteger) and arbitrary-precision decimal arithmetic (BigDecimal).
java.security	Provides the classes and interfaces for the security framework.
java.util	Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).

Uses of Random in java.math

Methods in java.math with parameters of type Random

static BigInteger BigInteger.probablePrime(int bitLength, Random rnd)
Returns a positive BigInteger that is probably prime, with the specified bitLength.

Methods in java.math with parameters of type Random
`static BigInteger`	`BigInteger.probablePrime(int bitLength, Random rnd)` Returns a positive BigInteger that is probably prime, with the specified bitLength.

Constructors in java.math with parameters of type Random

BigInteger(int bitLength, int certainty, Random rnd)
Constructs a randomly generated positive BigInteger that is probably prime, with the specified bitLength.

BigInteger(int numBits, Random rnd)
Constructs a randomly generated BigInteger, uniformly distributed over the range 0 to (2^numBits - 1), inclusive.
