Scala Map mkString()用法及代码示例


此方法与mkString()相同,但此处还添加了开始,分隔符和结束。

函数定义: defmkString(start:String, sep:String, end:String):String

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



范例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--

范例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--
