Blank console window after running Ruby code [message #996265]

I am all new in developing and I am trying to get things up and running.
I have developed the little test program called "Hello.rb":

class Hello
def Hello
puts "Hello Ruby World"
end
end

After running the program, the only thing I see in the "Console" is that "<Terminated> Hello.rb [Ruby Script] /usr/bin/ruby/" but the window is blank. I don't have any output in the Console: I do not see the output message "Hello Ruby World". Any idea why that is happening? (I use "Ruby 1.9.3″ and I use "Eclipse IDE for C/C++ Developers, Version: Juno Service Release 1″ where I have installed the "Dynamic Languages Toolkit Ruby Development Tools")

Funnily enough for the following program the output is correctly displayed in the Console:
class HelloYourName
print ('What is your name:')
name = gets()
puts ("Hello #{name}")
end

To have some output that method should be invoke actually, e.g. like this:

class Hello
def hello
puts "Hello Ruby World"
end
end

o = Hello.new
o.hello

But if you want just print something, then you can write only puts:

puts "Hello Ruby World"
