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。

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--
