Subject: Re: how can i use a ruby class in object way

Sorry ,i am not show it very clear.Please read this example again:

class Test
def Test.say_hello
puts "Hello from #{self.name}"
puts "hello from #{self.class}"
end
say_hello #i don't understand here
end



Normally,we can use a class anyplaces after defining it ,but in this 
example,i use a classmehod immediately after defining it "in class 
context".This is valid.I means calling a classmethod(not an intance 
method) in a class defintion--not after defining that class--is valid 
.Can you explain it for me? thank you !
