Mark Dacek updated LANG-1402:
-----------------------------
Description:
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
