带有分隔符的 Scala Map mkString() 方法和示例

此方法与mkString()方法相同，但此处还添加了一个分隔符。

Method Definition: def mkString(sep: String): String

Return Type: It returns the elements of the map as a string along with the separator between them.

示例 #1：

// Scala program of mkString()
// method with a separator
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating map
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying mkString method 
        val result = m1.mkString("/")
          
        // Displays output
        println(result)
    }
}

输出：

geeks -> 5/for -> 3/cs -> 2

示例 #2：

// Scala program of mkString()
// method with a separator
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating map
        val m1 = Map("geeks" -> 5, "for" -> 3, "geeks" -> 5)
          
        // Applying mkString method 
        val result = m1.mkString("/")
          
        // Displays output
        println(result)
    }
}

输出：

geeks -> 5/for -> 3
