Scala Map mkString()用法及代碼示例


此方法與mkString()方法相同,但此處還添加了分隔符。

函數定義: def mkString(sep:String):String

返回類型: It returns the elements of the map as a string along with the separator between them.



範例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) 
    } 
}
輸出:
geeks -> 5/for -> 3/cs -> 2

範例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) 
    } 
}
輸出:
geeks -> 5/for -> 3
