Ruby: How to make a public static method?

Question

In Java I might do:

public static void doSomething();

And then I can access the method statically without making an instance:

c         


        

Answer 1

There is one more syntax which is has the benefit that you can add more static methods

class TestClass

  # all methods in this block are static
  class << self
    def first_method
      # body omitted
    end

    def second_method_etc
      # body omitted
    end
  end

  # more typing because of the self. but much clear that the method is static
  def self.first_method
    # body omitted
  end

  def self.second_method_etc
    # body omitted
  end
end
