Scala Iterator toSeq() method with example

Last Updated : 13 Aug, 2019

The toSeq() method belongs to the concrete value member of the class Abstract Iterator. It is equivalent to the Seq method but this method is more faster.

Method Definition: val result = iter.toSeq Return Type: It returns the stated collection as a sequence.

Example #1:

Scala

// Scala program of toSeq()
// method

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating a Iterator 
        val iter = Iterator(2, 5, 7, 8, 9)
        
        // Applying toSeq method 
        val result = iter.toSeq
        
        // Displays output
        println(result)
        
    }
}

Output:

Stream(2, ?)

So, here a sequence is obtained. Example #2:

Scala

// Scala program of toSeq()
// method

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating an empty Iterator 
        val iter = Iterator()
        
        // Applying toSeq method 
        val result = iter.toSeq
        
        // Displays output
        println(result)
        
    }
}

Output:

Stream()

So, here an empty iterator is obtained as the stated iterator is empty.
