> There should be a safe way to retrieve a value from array without having to check for
null and length. It would be a very simple implementation but could save developers a great
deal of time in writing and testing.
>  
> Something like 
>  
> {code:java}
> String[] a = null;
> ArrayUtils.get(a, 5); //returns null
> a = new String[5];
> ArrayUtils.get(a, 10); // returns null
>  
> a[0] = "Hello World";
> ArrayUtils.get(a, 0); // returns "Hello World"
> {code}
>  
>  We could handle a few other cases - a default return value. The tricky/annoying thing
is the need to cast everything in order to make this
