What is the difference between Arrays.sort and Collections.sort?

[Anna Gabillet]

Except the fact that with the Arrays.sort we can sort the arrays of primitives?

Thanks!
I couldn't find that yet...

The java.util.Arrays sort() method is used to sort arrays; and java.util.Collections sort() method is used to sort Lists.
however, Collections.sort uses Arrays.sort internally! basically Collections.sort do cast from List to array(by invoking the toArray() method of List) for you.
