How does Hash work internally?

[veda84]

Hello guys,

How does Hash works internally,
Case1:

# Literal Hash
h0 = { ’one’ => 1, ’two’ => 2, ’three’ => 3} 

Case 2:

# Populating a hash
h1 = Hash.new » {}
h1[’gemstone’] = ’ruby’ 
h1[’fruit’] = ’banana’ 

When I try to print h0 in case 1:,
it prints as below
{"three"=>3, "two"=>2, "one"=>1}

Whereas in the Case 2 h1 prints as
{"gemstone"=>"ruby", "fruit"=>"banana"}


Why is the differences???

Thanks,
Veda

I'm not sure I understand your question, but hashes are not order specific. So, even though you define it as in case 1 (1,2,3) it may print out in a different order, as you have seen. The hash itself is unchanged, it just runs through the items in it's own order.
