RandomUtils (Cobble Lang 4.6.0 API)

java.lang.Object
- net.hasor.cobble.RandomUtils

```
public class RandomUtils
extends Object
```
Utility library that supplements the standard Random class.

Caveat: Instances of Random are not cryptographically secure.

Provides randomness between any two numbers, For example: arbitrarily large numbers, negative numbers

that may be a better choice for applications with more stringent requirements

public RandomUtils()
```
    RandomUtils instances should NOT be constructed in standard programming. Instead, the class should be used as RandomUtils.nextBytes(5);.
    
    This constructor is public to permit tools that require a JavaBean instance to operate.
