Scala SortedMap iterator method with example

Last Updated : 02 Nov, 2019

The iterator method is utilized to give an iterator.

Method Definition: def iterator: Iterator[(A, B)] Return Type: It returns a non-empty iterator for non-empty SortedMap and returns an empty iterator for empty SortedMap.

Example #1:

Scala

// Scala program of iterator
// method
import scala.collection.immutable.SortedMap

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2) 
        
        // Applying iterator method
        val result = m1.iterator
        
        // Displays output
        println(result)
    
    }
}

Output:

non-empty iterator

Example #2:

Scala

// Scala program of iterator
// method
import scala.collection.immutable.SortedMap

// Creating object
object GfG
{ 

    // Main method
    def main(args:Array[String])
    {
    
        // Creating a SortedMap
        val m1 = SortedMap( "cs" -> 2) 
        
        // Applying iterator method
        val result = m1.iterator
        
        // Displays output
        println(result)
    
    }
}

Output:

non-empty iterator
