List changes unexpectedly after assignment. How do I clone or copy it to prevent this?
... it:
new_list = old_list[:]
Alex Martelli's opinion (at least back in 2007) about this is, that it is a weird syntax and it does not make sense to use it ever. ;) (In his opinion, the next one is more readable).

Apache Commons is a really mature library, but it's also almost 10 years old, and targets Java 1.4. Guava was open sourced in 2007, targets Java 5, and thus Guava greatly benefits from the Java 5 features: generics, varargs, enums, and autoboxing.

Why would iterating over a List be faster than indexing through it?
...I wanted to print the value of each element, if I write this:

System.out.println(list.get(i));
}

head -> item1 -> item2 -> print item2
head -> item1 -> item2 -> it...
