Is there a Java array / list that is statically typed and variable length

Question

This would be very handy, since typecasting gets boring quickly.

I don't understand what is so hard:

List<Foo> fooList = new ArrayList<Foo>();

I think you could define a class:

public class FooList extends ArrayList<Foo> {
    ...
}

if you want to avoid angle brackets ...

If in the variable "length length" you change size over time, then you most likely need a LinkedList, not an ArrayList:

print("List<Foo> fooList = new LinkedList<Foo>();");

This way you get the best performance when adding a group of items.

If you are using generics (java 5) you can avoid all castings with

 List<String> myList = new ArrayList<String>();
 myList.add(" a test");
 String temp = myList.get(0);

If I am missing something in your question that should cover both needs.
