In this exercise, what is triggering the console to print “All systems go!”? Does a method execute automatically whenever it is declared public?

class Application
  attr_accessor :status
  def initialize; end
  # Add your method here!
  public
  def print_status
    puts "All systems go!"
  end
end
3

No method should execute if it hasn’t been called first.

Technically, nothing should be printed to the console.

4

That’s what I thought, but then don’t quite understand why “All systems go!” appears in the console.

5

Probably just to show you the expected result, so in the background the Learning Environment calls the method to render the message?
