Subject: with and without initialize method

Hi all,

I try to understand some concepts in Ruby. I define two classes, one
with and the other without initialize method.  In order to call the
methods defined in each class I need to call new/initialize method
first. Why is that?


Thanks,

Li

#####################
class X
  def hello_1
  puts 'Hello_1'
end
end

a=X.new
a.hello_1


####################
class Y
  def initialize
  end

  def hello_2
    puts'Hello_2'
  end
end

b=Y.new
b.hello_2

######screen output

>ruby test3.rb
Hello_1
Hello_2
>Exit code: 0
