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

// 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

// 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:
