Last Updated : 29 Jul, 2019

The iterator method is utilized to give an iterator.

Method Definition: def iterator: Iterator[A] Return Type: It returns a non-empty iterator for non-empty list and returns an empty iterator for empty list.

Example #1:

Scala

// Scala program of iterator
// method

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating a list
        val m1 = List(1, 2, 3, 4, 5)
        
        // Applying iterator method
        val result = m1.iterator
        
        // Displays output
        println(result)
        
    }
}

Output:

non-empty iterator

Example #2:

Scala

// Scala program of iterator
// method

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating an empty list
        val m1 = List() 
        
        // Applying iterator method
        val result = m1.iterator
        
        // Displays output
        println(result)
    
    }
}

Output:

empty iterator
