Scala Iterator mkString() method with example

Last Updated : 13 Aug, 2019

The mkString() method belongs to the concrete value member of the class Abstract Iterator. It is utilized to display all the elements of the collection in a string.
Method Definition:

val result = iter.mkString

Here, we are storing string in result variable.
Return Type:
It returns the string representation of the stated collection.
Example #1:

// Scala program of mkString() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(3, 6, 15, 19, 21) 
          
        // Applying mkString method 
        val result = iter.mkString 
          
        // Displays output 
        println(result) 
      
    } 
} 

Output:

36151921

Example #2:

// Scala program of mkString() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(0, 0, 1) 
          
        // Applying mkString method 
        val result = iter.mkString 
          
        // Displays output 
        println(result) 
      
    } 
} 

Output:
