测试时的代码是这样

1. a1 = TCItem.new(1, 1, 3)
   
2. a2 = TCItem.new(1, 2, 1)
   
3. a3 = TCItem.new(0, 0, 1000)
   
4. b1 = TCItem.new(1, 3, 1)
   
5. b2 = TCItem.new(2, 1, 1)
   
6. b3 = TCItem.new(3, 1, 1)
   
7. a = [a1, a2, a3]
   
8. b = [b1, b2, b3]
   
9. $reci = TCRecipe.new("test", a, b)
   
10. p $reci.name
    
11. p $reci.is_can_use
    
12. p $reci.list_of_material
    
13. p $reci.list_of_product

复制代码

结果打印出来的结果是
"test"
true
"无"
"无"
也就是说"原料"数组和“成品”数组没有被读入

求高手挑刺，到底是哪里出了问题

既然已经写了

1.   attr_accessor :kind
   
2.   attr_accessor :num
   
3.   attr_accessor :amount

复制代码

那个下面的那串

1.   def kind
   
2.     return @kind
   
3.   end
   
4.   def kind=(newkind)
   
5.     @kind = newkind
   
6.   end
   
7.   def num
   
8.     return @num
   
9.   end
   
10.   def num=(newnum)
    
11.     @num = newnum
    
12.   end
    
13.   def amount
    
14.     return @amount
    
15.   end
    
16.   def amount=(newamount)
    
17.     @amount = newamount
    
18.   end

复制代码

就不用了
其他的需要再看看XD

楼主之前是VB的程序员？代码没什么问题，不过有一个很严重，很容易被忽视的错误：

在Ruby里，判断相等应该是 == 方法，而不是 = 操作符。

比如，如果1等于1就应该写作 if 1 == 1 而不是if 1 = 1。否则，无论if后面的condition是什么，都会认为是true而执行then（此关键字通常被省略）后面的语句块

明白了……ORZ
