Ruby 如何访问此变量？

我有上面的代码…假设我然后写

class Player
  def getsaves
    print "Saves: "
    saves = gets
  end
  def initialize(saves, era, holds, strikeouts, whip)
  end
end

我想访问

getsaves

当我不在课堂范围内时，我该怎么做

j = Player.new(30, 30, 30, 30, 30)

正如您所写的那样，

saves

变量不仅无法从类范围之外访问，而且在

getsaves

方法的末尾超出了范围

您应该这样做：

puts saves variable that is inside getsaves

现在，您只需使用

j.saves

访问

@saves

变量即可

class Player
  def getsaves
    print "Saves: "
    @saves = gets # use an instance variable to store the value
  end
  attr_reader :saves # allow external access to the @saves variable
  def initialize(saves, era, holds, strikeouts, whip)
  end
end
