当我运行我的代码时，我收到以下错误:
Card.rb:51: class definition in method body
Card.rb:74: syntax error, unexpected end-of-input, expecting keyword_end
我检查了第 51 行和第 74 行以及所有相关的 block ，但我找不到任何错误。似乎所有 end 语句都对齐了。当我取出 Card 类中的私有(private)方法时，错误停止，但我无法准确指出错误所在。我有正确数量的结束语句，为什么我收到 方法主体中的类定义 错误
class Card
attr_reader :suit, :rank
def initialize(suit, rank)
@suit = suit
@rank = rank
end
def face_card?
@rank > 10
end
def to_s
suitName = suitString()
rankName = rankString()
rankName " of " + suitName
end
private
def rankString
if @rank <= 10
@rank
else if @rank == 11
"Jack"
else if @rank == 12
"Queen"
else if @rank == 13
"King"
else
"Unknown rank"
end
end
def suitString
if @suit == :spades
"Spades"
else if @suit == :clubs
"Clubs"
else if @suit == :hearts
"Hearts"
else if @suit == :diamonds
"Diamonds"
else
"Unknown Suit"
end
end
end
class Deck
def initialize
@cards = []
suits = [:hearts, :diamonds, :spades, :clubs]
suits.each do |suit|
12.times do |rank|
@cards << Card.new(suit, (rank + 1))
end
end
end
def shuffle
@cards.shuffle!
end
def draw(n = 1)
@cards.pop(n)
end
def count
@cards.count
end
end
