ruby - 获取 `initialize' : wrong number of arguments(1 for 0) (ArgumentError) for simple ruby app

Question

这是我的第一个 ruby 应用程序。我是一个堆栈溢出处女......当我运行以下程序时:

class NameApp

def intialize(name)
    @names = []
end

def name_question
    print "What is your name? "
    answer = gets.chomp
    @names += answer.to_s
    puts "The number of characters in your name is " + names.length
end


def name_length
    if @names.length > 25 then 
        print "Your name is longer than 25 characters."
    else 
        print "Your name is too short."
    end
end

end

name_app = NameApp.new("Test1")
name_app.class # => NameApp

name_app.name_question
name_app.name_length

我得到这个简单的错误消息结果:

name.rb:26:in `initialize': wrong number of arguments(1 for 0) (ArgumentError)
from nameapp.rb:26:in `new'
from nameapp.rb:26:in `<main>'

你能帮我解决问题吗？

你拼错了“initialize”。我刚开始的时候也这样做过几次，这很难调试。为什么 ruby​​ 没有将它命名为“init”，我永远不会知道。
