JDKRandom (Apache Commons RNG Core 1.5 API)

java.lang.Object
- org.apache.commons.rng.core.BaseProvider
- - org.apache.commons.rng.core.source32.IntProvider
  - - org.apache.commons.rng.core.source32.JDKRandom

All Implemented Interfaces:

RandomIntSource, RestorableUniformRandomProvider, UniformRandomProvider
```
public class JDKRandom
extends IntProvider
```
A provider that uses the Random.nextInt() method of the JDK's Random class as the source of randomness.
Caveat: All the other calls will be redirected to the methods implemented within this library.

The state of this source of randomness is saved and restored through the serialization of the Random instance.

Since:

1.0
