---

This library contains Iterators and Iterables for all primitive types. It also replaces native primitive iterators: 

`java.util.PrimitiveIterator.OfInt`, `java.util.PrimitiveIterator.OfLong`, `java.util.PrimitiveIterator.OfDouble`.

## How to use

Maven:

```xml

  com.plugatar

  mjpi

  1.0

```

Gradle:

```groovy

dependencies {

    compile 'com.plugatar:mjpi:1.0'

}

```

| `short`   | `ShortIterator`   | `ShortIterable`   |
