Collections.class methods anachronisms?
The Collections class is supposed to, among other things, return
type safe collections from existing collections with static methods
such as .checkedList().
My question is: What is so special about these static methods since
we can do the same thing by declaring the original list generically
with a type like <String>? I mean, once you create the list with
<String> the compiler will no longer allow you to add, say,
Integer to the list. So what purpose does .checkedList() provide
in that context?
Maybe it's all about backward compatibility?
