By being in List interface, they are easier to find. In an external 
class, they have a very small value comparing to current constructors. 
Static methods from classes like Collections, Arrays are not useful for 
beginners because they are impossible to find in a very big API like Java).

But, if you know that all lifecycle (factory for creation, change of 
content, etc.) of a List is managed by List interface, you know exactly 
where to find the solution of your problem. You can even publish a 
subset of javadocs of Java without implementing classes like ArrayList, 
LinkedList, etc. which will be much more clear for learning Java and 
attracting new users.

A defender method in interface can too be a method in Collections class 
(even allowing specialized implementation with a service to be 
implemented), but this is always more difficult to find and it give 
globally a very complex API.
