Scala Iterator mkString()用法及代碼示例


此方法也與mkString()方法相同,但此處帶有起點,分隔符和終點。

函數定義: def mkString(start:String, sep:String, end:String):String

Where, start is the starting string, sep is the separator string and end is the ending string.



返回類型: It returns the string representation of the stated collection along with a start, a separator and an end.

範例1:

// Scala program of mkString() 
// method with a start, end  
// and a separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(1, 2, 3, 5) 
          
        // Applying mkString method  
        val result = iter.mkString("*", "0", "*") 
          
        // Displays output 
        println(result) 
      
    } 
}
輸出:
*1020305*

其中,開始是*,sep是0,結束也是*。範例2:

// Scala program of mkString() 
// method with a start, end  
// and a separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(1, 2, 3, 5) 
          
        // Applying mkString method  
        val result = iter.mkString("#", "*", "#") 
          
        // Displays output 
        println(result) 
          
    } 
}
輸出:
#1*2*3*5#
