Subject: what's String.hash

irb(main):038:0* x="hello"
=> "hello"
irb(main):039:0> x.object_id
=> 69352346
irb(main):040:0> x.hash
=> 267522041
irb(main):041:0> y="hello".intern
=> :hello
irb(main):042:0> y.object_id
=> 246184
irb(main):043:0> y.hash
=> 246184


What's the meanings of String.hash method?
does it have any relation to object_id? Thanks.
