JDKRandomWrapper (Apache Commons RNG Simple 1.5 API)

java.lang.Object
- org.apache.commons.rng.simple.JDKRandomWrapper

All Implemented Interfaces:

UniformRandomProvider
```
public final class JDKRandomWrapper
extends Object
implements UniformRandomProvider
```
Wraps a Random instance to implement UniformRandomProvider. All methods from the Random that match those in UniformRandomProvider are used directly.
This class can be used to wrap an instance of SecureRandom. The SecureRandom class provides cryptographic random number generation. The features available depend on the Java version and platform. Consult the Java documentation for more details.

Note: Use of java.util.Random is not recommended for applications. There are many other pseudo-random number generators that are statistically superior and often faster (see RandomSource).

1.3
