How to get a specific output iterating a hash in Ruby?

by 
hash.each do |key, array|
  puts "#{key}-----"
  puts array
end

Regarding order I should add, that in 1.8 the items will be iterated in random order (well, actually in an order defined by Fixnum’s hashing function), while in 1.9 it will be iterated in the order of the literal.
