scala - 如何在scala中循环遍历元组

Question

我在 scala 中有一个元组

val captainStuff = ("One", "Two", "Three", "Four", "Five")

我如何遍历 for 循环？遍历列表和 map 很容易。但是如何循环元组。

谢谢!!

Answer 1

您可以将其转换为迭代器，例如:

val captainStuff = ("One", "Two", "Three", "Four", "Five")

captainStuff.productIterator.foreach(x => {
  println(x)
})

顺便说一句，这个问题是重复的:
