The Apache Commons RNG project provides pure-Java implementation of pseudo-random generators.

Documentation
-------------

More information can be found on the [Apache Commons RNG homepage](https://commons.apache.org/proper/commons-rng). The Javadoc for each of the modules can be browsed:

- [Commons RNG Client API](https://commons.apache.org/proper/commons-rng/commons-rng-client-api/apidocs/)
- [Commons RNG Core](https://commons.apache.org/proper/commons-rng/commons-rng-core/apidocs/)
- [Commons RNG Simple](https://commons.apache.org/proper/commons-rng/commons-rng-simple/apidocs/)
- [Commons RNG Sampling](https://commons.apache.org/proper/commons-rng/commons-rng-sampling/apidocs/)

Questions related to the usage of Apache Commons RNG should be posted to the [user mailing list](https://commons.apache.org/mail-lists.html).

Getting the latest release
--------------------------
You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-rng/download_rng.cgi).

Alternatively, you can pull it from the central Maven repositories:

```xml
<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-rng-simple</artifactId>
  <version>1.6</version>
</dependency>
<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-rng-sampling</artifactId>
  <version>1.6</version>
</dependency>
```

Building
--------

Building requires a Java JDK and [Apache Maven](https://maven.apache.org/).
The required Java version is found in the `pom.xml` as the `maven.compiler.source` property.

From a command shell, run `mvn` without arguments to invoke the default Maven goal to run all tests and checks.

Contributing
------------

We accept Pull Requests via GitHub. The [developer mailing list](https://commons.apache.org/mail-lists.html) is the main channel of communication for contributors.
There are some guidelines which will make applying PRs easier for us:
+ No tabs! Please use spaces for indentation.
+ Respect the existing code style for each file.
+ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
+ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn```.

If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas).
You can learn more about contributing via GitHub in our [contribution guidelines](CONTRIBUTING.md).
