Line 547:

In [[Ruby (programming language)|Ruby]], constructors are created by defining a method called <code>initialize</code>. This method is executed to initialize each new instance.

<source lang="rubyrbcon">

irb(main):001:0> class ExampleClass

irb(main):002:1> def initialize

irb(main):003:2> puts "Hello there"

irb(main):004:2> end

irb(main):005:1> end

end

=> nil

irb(main):006:0> ExampleClass.new # => "Hello there"

Hello there

=> #<ExampleClass:0x007fb3f4299118>
