小编The*_*ilz的帖子

我在RubyMine中有这两个类:

book.rb

 class Book
   def initialize(name,author)
   end
 end

test.rb

require 'book'
class teste
   harry_potter = Book.new("Harry Potter", "JK")
end

当我运行test.rb时,我收到此错误:C:/Users/DESKTOP/RubymineProjects/learning/test.rb:3:in'from <class:Test>': uninitialized constant Test::Book (NameError) from C:/Users/DESKTOP/RubymineProjects/learning/test.rb:1:in-e:1:in load' from -e:1:in'

如果符合条件,此行代码会打印您的帐户余额:

p account.balance if num_account == account.num_account && agencia == account.agencia

我希望else在没有重复所有条件的情况下满足这些条件.你能用这段代码帮我吗？
