Scala Iterator seq() method with example

The seq() method belongs to the concrete value members of the class Iterable. It is helpful in visualizing the sequential view of the stated collection. It has a time complexity of O(1).

  • Method Definition:

    def seq: Iterator[A]
    
  • Return Type:
    It returns a sequential view of the iterator.

Example :



filter_none

code

// Scala program of seq()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Declaring an iterator
        val iter = Iterator(3, 4, 5, 6, 7)
          
        // Applying seq method in 
        // for loop
        for(n<-iter.seq)
        {
              
            // Displays output
            println(n)
  
        }
    }
}
