Scala用逗号分隔数组，每个项目用引号引起来 [英] Scala split Array by comma and each item by quotes

问题描述

我需要在scala中用逗号分割数组，并用引号将每个项目分割。

I need to split an array by comma in scala and each item by quotes.

scala提供mkString来分割项目，下面的示例使用它：

scala offers mkString to split items, the following example uses it:

val args = Array("Hello", "world", "it's", "me")
val string = args.mkString(",")

结果为：

Hello,world,it's,me

但我需要用引号将每个元素括起来，如以下示例所示：

but I need each element enclosed by quotes as in the following example:

"Hello","world","it's","me"

我可以使用以下地图来实现它

I can implement it using a map like the following one

args.map(entry => s""""${entry}"""" ).mkString(",")

是否有任何内置操作以更礼貌的方式执行相同操作？

is there any builtin operation that does the same in a more polite way ?

谢谢！

推荐答案

或者可以使用 mkString ，并提供前缀和后缀如下：

Or maybe use the version of mkString with option to provide prefix and suffix as below:

val args = Array("Hello", "world", "it's", "me")
args.mkString(""""""", """","""", """"""")
