带有开头、分隔符和结尾的 Scala Map mkString() 方法示例

此方法与mkString()相同，但此处还添加了开始、分隔符和结束。

Method Definition: defmkString(start: String, sep: String, end: String): String

Return Type: It returns the elements of the map as a string along with a stated start, separator and an end.

示例 #1：

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

输出：

>>>geeks -> 5|for -> 3--
