Why would iterating over a List be faster than indexing through it?


Reading the Java documentation for the ADT List it says:




The List interface provides four methods for positional (indexed) access to list elements. Lists (like Java arrays) are zero based.

Thus, iterating over the elements in a list is typically preferable to indexing through it if the caller does not know the implementation.
