Scala：来自'if'语句的奇怪结果

Question

尝试使用Scala 2.10.3'条件'语句：

scala> val index = "male-names"
index: String = male-names

scala>  val kind = if (index == "male-mames") "mn" else "fn"
kind: String = fn

为什么'善'得到“fn”而不是“mn”？

另一方面，以下情况仍然存在：

scala> index == "male-names"
res28: Boolean = true

scala> index
res29: String = male-names

Answer 1

scala> val index = "male-names"
index: String = male-names

有一点拼写错误

scala>  val kind = if (index == "male-mames") "mn" else "fn"
                                      ^
kind: String = fn
