scala如何在另一个内部调用方法？

Question

我的process（修剪字符串列表）函数可以单独运行，但是当我在另一个函数内部调用时，行为会有所不同。

def process (s: Any*): String = {
    val chaine= s.map(_.toString).toList
    println(s" Convert to string: $chaine")
    val trimmed = chaine.map(_.trim).toList
    println(s"Trimmed: $trimmed")
    trimmed.mkString(",")
}

def func(s: Any*): String = {
    val processed = process(s)
    processed
}

process("xyz ","111  ")
func("xyz ","111  ")

结果

Convert to string: List(xyz , 111  )
Trimmed: List(xyz, 111)

Convert to string: List(WrappedArray(xyz , 111  ))
Trimmed: List(WrappedArray(xyz , 111  ))
