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:

filter_none

brightness_4
code

// 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:

filter_none

// 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.
