## 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.

Constructors in java.math with parameters of type Random
`BigInteger(int numBits, Random rnd)` Constructs a randomly generated BigInteger, uniformly distributed over the range `0` to `(2numBits - 1)`, inclusive.
`BigInteger(int bitLength, int certainty, Random rnd)` Constructs a randomly generated positive BigInteger that is probably prime, with the specified bitLength.

Uses of Random in java.security

Subclasses of Random in java.security
`class` | `SecureRandom` This class provides a cryptographically strong pseudo-random number generator (PRNG).

Uses of Random in java.util

Methods in java.util with parameters of type Random
`static void` | `Collections.shuffle(List list, Random rnd)` Randomly permute the specified list using the specified source of randomness.
